Holdfast Gutter Extrusion Kit

Short Product Summary

The Holdfast Gutter Extrusion Kit bolts onto a trailer, canopy or box body with no factory-fitted rain gutter, giving a Holdfast Classic Roof Rack's gutter-mount feet something to clamp onto. It comes in white or black aluminium to match the body it's fitted to.

Why This Product

A Classic Roof Rack's gutter feet need an actual gutter to grip, and plenty of modern canopies and conversions skip that gutter to keep their body lines clean. This extrusion kit bolts on with a sealing strip against water ingress, so a rack that would otherwise have nothing to clamp onto gets a proper mounting edge instead.

Key Features

• Creates a mounting gutter – gives Classic Roof Rack gutter feet an edge to clamp onto
• Aluminium extrusion – matches the load rating of a factory vehicle gutter
• Bolt-on fitting with a sealing strip – keeps water from getting in at the join
• White or black finish – pick the colour that matches your canopy or trailer body
• No drilling into the rack itself – the rack clamps onto the extrusion using its standard feet

Ideal For

• Canopy and game-viewer conversion owners whose body doesn't have a factory rain gutter for a roof rack to grip.
• Trailer and panel van owners fitting a Classic Roof Rack where there's no gutter to mount to.
• Anyone matching their vehicle's finish since the kit comes in white for lighter bodies or black for darker ones.

Optional Fitment / Upgrade Notes

This kit is colour-matched to your vehicle, so check these points before ordering:

• It's made to mount a Holdfast Classic Roof Rack's gutter feet, so confirm that's the rack you're fitting before ordering.
• Pick white for a lighter canopy or trailer body, or black for a darker or aftermarket one — both are the same aluminium underneath.
• It bolts onto the body itself, not the rack, so you'll still need the roof rack kit and its feet separately.
