3318 or 3138

A quick learner from San Francisco says:

These are aluminum sliding door rollers. If you can identify it would be great. The only numbers on them are 3318. If you find them please send a price and delivery to San Francisco.

Hi Kevin, may we have some dimensions of the housing and wheel diameter, thickness and axle? This should help us narrow it down. Thanks.

A quick learner from San Francisco says:
These rollers were fitted to sliding aluminum doors in a house built in France in 1984. I am travelling at the moment but will get back to France on May 16th and measure. I will also take a couple of pics of the aluuminum profile.

Thanks for the help so far and you quick responses.

Hi Paul,

I attach a sketch with rough dimensions and some pics. Apparently this is a fixed roller with both parts bearing the number 3318, the adjustable version I have yet to find. I am beginning to think that It may be obsolete, if so, I will be forced to find a replacement. Anyway, your help is much appreciated,

Best regards

Kevin

Thanks for getting back to us, Kevin.  We do offer a one piece die cast roller assembly, we'd like for you to take a look at, our 87-075. It is showing similar dimensions to yours. Look it over carefully to see if you think this could make a good alternative for you.
