Key Features

• Acetal construction
• Overall 21.2 x 47.2mm
• Australian stock, dispatched within 1 business day

Fits & Replaces

• Direct replacement for old Alumalite and most other Australian aluminium sliding window carriages of this pattern.
• Fit is decided by the 47.2mm carriage length and the 21.2mm body width, and by the convex roller profile — a convex roller needs a matching grooved track, so check the track shape as well

Specifications

• TradeBase SKU: CAR47ACE
• Material: Acetal
• Overall size: 21.2 x 47.2mm

Installation Tips

• Check the track before you fit. File any burrs or flat spots smooth — a damaged track will chew out a new roller within weeks.
• Clean all grit and old grease out of the track. Grit is what kills a roller, not load.
• Replace carriages in pairs. A new roller running against a worn one carries uneven load and both wear out early.
• Fit the rear carriage first, then set the front carriage to get your clearance.
• Adjust last to bring the sash parallel with the frame, working from the lock side.
• Slide the sash through its full travel before refitting stops or flyscreens.

Care & Maintenance

• Use a dry lubricant only — silicone or dry PTFE. Oil and grease hold dust and grind the roller.
• Sweep the track out every few months, more often in coastal or dusty areas.
