I have a 1956 aluminum sliding door, single pane. Manufacturer is Crestview Products Limited. California. I can only find a roller adjustment screw hole on one end of the sliding door. The inside end.
Is it possible that there is only one adjustment point?Are you familiar with this manufacturer? I cannot find anything online.Just wanting to adjust the rollers as the door is quite sticky.
Thank you.
I have seen the name Crestview before, though I am unfortunately not familiar with what kind of roller hardware their doors use. That said most patio doors have two roller assemblies, which means you would have two points of adjustment (one on one corner of the door, and another on the opposite side).
I cannot say for sure if Crestview uses a strange, alternate system but it would be very strange if they did. Does the opposite side of the door have at least a hole where an adjustment screw could go? If so then it's possible the roller is missing entirely.
Sounds good, George! I'll be here when you get them.
I see your two photos showing the front and back end of the patio door at the bottom. You're right: it looks like only the one end is adjustable looking at the recessed hole at the bottom of the door. The other side of the door must have a "fixed" roller which cannot be adjusted.
You need to look inside that hole at the one end to see what type of screw driver you will need to adjust that roller. It should be either a Philips or a slot type screw. Also have someone help you when adjusting the roller to lift up the door to take the weight off the wheel when adjusting. Since only one side is doing the work, it's going to take some elbow grease.
