Universal Mounting Kit Installation Guide

The Slender Fender comes with a post clamp receiver and a vertical slotted post (see diagram). Both parts have been designed to fit virtually all wheelchair brands.

Post clamp receiver can be mounted to both round and oblong tubular frames or can be attached directly to existing hardware, such as a mud guard.

You can position the fender as close to the tire as you wish. This is a feature unique to the Slender Fender.



Tools required:
+ Drill (suitable for metal) with 1/4" bit
+ Allen key (supplied) 

Installation Steps

Remove seat sling and install spacers

Remove seat sling and install 3/8” spacers (provided) in between the top of the seat rail and fabric seat sling underside.

Attach the Slender Fender post receiver clamp

Attach the Slender Fender post receiver clamp to the wheelchair seat rail as close as possible to the wheel centre. Slide in the vertical post with the widest slot on the post facing inwards towards the seat sling. 

* Please note the clamp clamp has two positions: short and tall to accommodate 20” to 26” diameter wheels respectively. Choose the position best suited for your install. 

Position the Slender Fender onto the vertical post

Check lateral clearance: Position the Slender Fender onto the vertical post for a dry test fit. Make sure the wheel spokes don’t make contact with the fender surface. If there is contact reposition the wheel laterally on its’ axle and re-tighten securely.

Place fender on top of the tire

Place your fender on top of the tire using spacers (provided) to establish equal spacing between the top of the tire and the inside of the fender. While holding the fender securely against the vertical post, drill a ¼” diameter hole through the wide slot and through the plastic fender approximately in the middle of the slot.

Install lock nut into the wide slot

Install the ¼”-20 lock nut (provided) into the wide slot of the vertical post. Put the ¼”-20 screw (provided) through the plastic fender first and then mate it with lock nut. Tighten the ¼-20 screw enough so that you can slide the fender vertically while you position it over the tire.

Adjust and confirm position

Double check the clearance between the tire and the fender shell to be certain confirm that’s your preferred position for accessing the push rim.

Lock it in

Holding the fender firmly, drill the second hole through the ¼” clearance hole at the top of the vertical post. Install the next 1 ¼-20 screw and lock nut (provided). Tighten both screws firmly with your 5/32”Allen key.
