When a sliding security or flyscreen door starts dragging or jumping off its track, a worn bottom wheel is usually why, and this is the replacement.
It's the Cowdroy S964 sheave assembly, a bottom rolling carriage with a 39mm concave wheel in black nylon, rated to 50kg per door, made for aluminium framed doors running on a Cowdroy track. Sheaves look alike but come in a lot of sizes, so lift the door out and measure the old wheel and its housing before you buy, and replace both at the bottom so the door sits level.
One sheave per card. Full specs are in the tabs below, and if you're not sure it matches, bring the old one in to 34-52 Milnes Rd, Strathalbyn or call us on (08) 8536 4333.
