Sliding door rollers and carriages for Jason, Stegbar, Boral, Dowell, Bradnams and Comalco. OEM-grade replacements, Perth stock, ships Australia-wide.

Slide Master Hardware in Wangara WA holds Perth’s deepest stock of replacement sliding door rollers and carriage assemblies. Our range covers the major Australian residential and commercial aluminium-frame brands — including profiles dating back to the 1970s through current production frames — with a focus on OEM-grade parts that match the original wheel material, dimensions, and load rating of the part you’re replacing.

How to identify the right sliding door roller. Most sliding door rollers are stamped with a part code (commonly a GM-prefix on Slide Master Hardware products) or a brand identifier on the carriage body. If your old roller has no markings, the most reliable identification path is photographic. Pull the failed roller out, place it on a plain surface, and photograph the side profile, the wheel-and-carriage assembly together, and any visible mounting holes. Note the door brand if you know it, the approximate year the door was installed, and whether the wheel runs on a flat track or a V-groove. Our Wangara team identifies several hundred parts a month from photos alone — there is no charge for the identification service.

Common signs your rollers need replacing. The most frequent early symptom is the door dragging or feeling heavy to slide, particularly toward the centre of the track. As wear progresses, you may hear a popping or grinding sound when the door moves, see visible scuff marks on the threshold, or find the door catching on the bottom track. In severe cases the door can ride up and jump off the track entirely. Worn rollers also stress the door frame, so addressing them early avoids more expensive repairs.

Installing replacement sliding door rollers. Roller replacement is straightforward on most residential aluminium doors and usually takes 15–30 minutes per door. If you prefer a visual walkthrough, follow our step-by-step replacement walkthrough. You’ll need to lift the door panel off the track, unscrew the existing carriage assembly from the bottom of the panel, fit the new roller in the same orientation, and refit the panel. Detailed brand-specific guidance is available on our Jason, Stegbar, Boral, and Comalco brand pages.

Frequently asked questions

Can you replace sliding door rollers? Yes — sliding door rollers are a serviceable part designed to be replaced when worn. The roller and carriage assembly unscrews from the bottom of the door panel and a like-for-like replacement reinstalls the same way. Most homeowners can complete the swap themselves in 15–30 minutes per door with basic tools. Our illustrated installation walkthrough shows the full sequence for Dowell, Boral, Stegbar, Bradnams, Comalco, Jason and Trimview doors.

How do I know what rollers I need for my sliding glass door? Match by brand, profile, and wheel type. If the old roller has no markings, send us a clear photograph showing the side profile, wheel-and-carriage assembly together, and the mounting hole pattern. Our Perth team identifies the correct replacement at no charge.

What are the common problems with door sliders? Worn rollers are the most frequent cause of sliding door problems — symptoms include the door dragging, feeling heavy, popping or grinding when moved, jumping off the track, or scuffing the threshold. Roller wear is often misdiagnosed as a track or alignment problem when in fact the wheels themselves have failed.

Are sliding patio door rollers universal? No — sliding patio door rollers are brand-specific and often profile-specific within a brand. Jason, Stegbar, Boral, Dowell, Bradnams, and Comalco doors all use different roller designs, mounting methods, and wheel diameters. Universal-fit rollers exist but rarely match OEM performance; brand-matched replacements last longer and run more quietly.
