Multiflex K17 Stainless Steel Universal Quick Release 33c Control Cable Clamp

The Multiflex K17 Stainless Steel Quick Release Clamp is a hook-style mounting bracket for compatible standard and EDGE universal mechanical control cables. Its locking retainer allows the cable to be released and lifted out without dismantling the complete bracket, simplifying installation, inspection and cable replacement. Multiflex identifies the K17 for marine and industrial applications and specifically lists compatibility with its 301 and 305 industrial control cables.

What Is This Control Cable Clamp Used For?

The Multiflex K17 secures the stationary outer section of a compatible mechanical control cable to a rigid support.

Holding the cable outer casing in position allows the inner member to travel in a push-pull direction and transfer movement between a control lever and the connected mechanism.

The K17 can be used as part of a correctly specified:

• Gear-shift control installation
• Throttle-control installation
• Engine remote-control system
• Gearbox remote-control system
• Industrial equipment control
• Vehicle or machinery control
• Replacement universal control cable installation
• Standard universal cable installation
• EDGE low-friction universal cable installation

The K17 is a mounting and retaining component. It does not generate cable movement and does not replace the control lever, cable or linkage fitting.

This listing is for:

• One Multiflex K17 stainless-steel quick-release cable clamp
• Integrated quick-release locking retainer
• Multi-point mounting bracket

The exact loose-fastener contents are not itemised in the available Multiflex product data.

Not included unless expressly stated:

• Control cable
• Shift or throttle control lever
• Engine-side linkage fitting
• Gearbox-side linkage fitting
• Clevis
• Ball joint
• Eye end
• Threaded cable terminal
• Separate structural support
• Installation-specific mounting bolts
• Washers or nuts

• Other control-system hardware

Which Control Cables Are Compatible?

Multiflex describes the K17 as suitable for:

• Standard universal control cables
• EDGE universal control cables
• Multiflex 301 industrial control cables
• Multiflex 305 industrial control cables

The selected cable must have a mounting ferrule or outer-casing interface that fits securely within the K17 retainer.

Correct fitment depends on:

• Cable manufacturer
• Cable model
• Cable outer-casing dimensions
• Cable mounting-ferrule dimensions
• Required cable travel
• Support-bracket position
• Cable operating direction
• Available installation space
• Minimum cable bend radius

Does the K17 Fit 33C / 3300 Control Cables?

The K17 uses the same general single-hook mounting format commonly used with universal 33C / 3300-series control cables.

Comparable Ultraflex and SeaStar single-hook brackets are specifically listed for standard, premium and low-friction 33C cables, including Multiflex standard and EDGE 33C cables.

However, the official Multiflex K17 product data do not specifically use the terms 33C, 3300, EC-133 or EEC-133. They instead specify standard or EDGE universal cables and the 301/305 industrial families.

The K17 can therefore be described as the Multiflex equivalent type of universal quick-release hook clamp, but exact 33C cable fit should be confirmed from the cable mounting ferrule before installation.

Is the Multiflex EC-133 Cable Compatible?

The Multiflex EC-133 is a universal 3300-series marine control cable with a standard clamp-style mounting arrangement.

The K17 manufacturer data do not expressly name EC-133 compatibility. Although the K17 is intended for standard universal cables and competitor replacement applications, EC-133 fit should be physically confirmed before it is presented as an unconditional direct-fit combination.

Check:

• Cable mounting-ferrule diameter
• Ferrule length
• Retainer engagement
• Cable alignment
• Required cable movement
• Support-bracket position

Is the Multiflex EEC-133 EDGE Cable Compatible?

The Multiflex EEC-133 is the EDGE low-friction version of the universal 3300 control cable.

Multiflex states that the K17 accepts an EDGE universal control cable, but the K17 product data specifically name the 305 industrial cable rather than the marine EEC-133.

This supports the K17's use with the EDGE universal cable format, but the exact EEC-133 mounting interface should still be checked before installation.

Is the K17 the Multiflex Equivalent of the Ultraflex L31?

Yes, the K17 is the closest Multiflex functional equivalent to the:

• Ultraflex L31
• SeaStar / Teleflex TX036174 single-hook bracket

The K17 and L31-style products perform the same general task: securing one compatible universal control cable with a quick-release locking hook.

The K17 should still be described as a functional equivalent rather than a confirmed dimensional cross-reference because Multiflex does not publish:

• An official Ultraflex L31 cross-reference
• Overall K17 dimensions
• Mounting-hole diameters
• Mounting-hole centres
• Base dimensions
• Bracket height

Confirm the existing mounting holes and available installation space before replacing an L31 or SeaStar bracket with a K17.

How Does the Quick-Release Clamp Work?

The K17 uses a locking hook or retainer to hold the control cable in its mounting position.

1. Return the connected control mechanism to a safe position.
2. Release the K17 locking retainer.
3. Lift the cable mounting section out of the bracket.
4. Inspect, adjust or replace the cable as required.
5. Refit the cable in the correct position.
6. Fully engage the retaining lock.
7. Test the complete control system before use.

What Is the Purpose of the Multi-Hole Bracket?

Manufacturer imagery shows the K17 with several mounting holes and a slotted fixing position.

This mounting arrangement allows the installer to select a fixing position that provides:

• Correct cable alignment
• Adequate linkage clearance
• Access to the quick-release retainer
• Suitable cable approach angle
• Secure attachment to the supporting structure
• Appropriate distance from moving machinery

Multiflex does not publish the individual hole sizes or centres. The bracket should be checked against the intended mounting surface before drilling.

Does the K17 Hold One or Two Control Cables?

The K17 is a single-hook clamp intended to retain one compatible control cable.

A typical single-engine mechanical remote control may use:

• One cable for gear shift
• One cable for throttle

Where both cables require quick-release support, the installation may require:

• Two K17 clamps
• Separate mounting positions
• A purpose-designed twin-cable bracket
• Another correctly specified mounting arrangement

The K17 should not be described as a double-hook or twin-cable bracket.

Are the K17 Dimensions 40 x 25mm?

Multiflex does not publish confirmed K17 dimensions in the available product data.

The equivalent SeaStar/Teleflex single-hook bracket is specified with:

• Base length: 40mm
• Base width: 25mm
• Height: 35mm

The Ultraflex L31 is also commonly specified with a 40 x 25mm base. These measurements should be treated as competitor-reference dimensions, not confirmed Multiflex K17 dimensions.

Do not add 40 x 25mm as a definitive K17 specification unless the physical K17 has been measured or a current Multiflex drawing confirms it.

Is the K17 a Cable-End Linkage Fitting?

No. The K17 secures the stationary outer section of the control cable.

It does not connect the moving inner cable to the:

• Gear selector
• Throttle arm
• Engine linkage
• Gearbox linkage
• Remote-control lever
• Carburettor linkage
• Fuel-control mechanism

A separate connection component may be required, such as:

• Ball joint
• Clevis
• Eye end
• Pivot
• Threaded adaptor
• Engine-specific connection kit

Is the Mounting Hardware Included?

The available Multiflex product data do not provide an itemised package-contents list.

The K17 bracket and its integrated quick-release mechanism form the product, but the following should not be represented as included without checking the supplied package:

• Mounting bolts
• Washers
• Locknuts
• Backing plate
• Structural support bracket
• Cable-end fittings
• Linkage hardware

Installation and Safety

Before installing the Multiflex K17:

• Confirm that the product is the K17 quick-release hook clamp
• Verify compatibility with the selected control cable
• Check the cable mounting ferrule against the K17 retainer
• Confirm EC-133 or EEC-133 fit where used in a marine installation
• Mount the K17 to a rigid structural support
• Select fixing points that provide correct cable alignment
• Use corrosion-resistant mounting fasteners
• Do not mount the bracket to an unsupported flexible panel
• Ensure the cable approaches the clamp without side loading
• Maintain the cable manufacturer's minimum bend radius
• Keep bends as large and gradual as possible
• Do not kink, twist or crush the control cable
• Keep the cable away from exhaust components and excessive heat
• Protect the cable from sharp edges and abrasive surfaces
• Keep the bracket and cable clear of belts, pulleys and moving machinery
• Ensure the cable is fully seated in the retainer
• Fully engage the quick-release lock
• Confirm that the cable cannot lift out during operation
• Check that the cable inner moves freely
• Test the control through its complete operating range
• Confirm positive forward, neutral and reverse selection where used for shifting
• Confirm that the throttle returns fully to idle
• Inspect the hook, lock, bracket and fasteners regularly
• Replace the K17 if it is bent, cracked, loose or excessively corroded
• Do not operate the control system if the cable binds or has excessive free movement

Engine shift and throttle controls are safety-critical systems. Installation and adjustment should be completed according to the current Multiflex, control, engine and gearbox instructions by a competent technician.
