Rollers for " Standard Building Components " Montreal Canada patio sliding doors. No. SCHL7123

Thanks for reaching out to us. I'm afraid we don't have an identical match for your roller. The 81-133, 81-270, and 81-275 come to mind but they're still very different. Have a look and see if you think one of them could work for your door.

If not and your old roller housing is in good shape, have a look at the 81-266 and 81-272 roller and axle kits along with the related videos. 

I'm sorry to say we don't sell a wheel with these specifications. The best we can offer is the 81-228, 81-237, and the 81-236A along with the axle kit 81-310. All these wheels take a 1/4" axle but see what you think.
