Questions about this item

What door frame width and material do I need for the 9/16 in. wide U-back housing to fit?

The housing is 9/16 in. wide, 1-1/16 in. tall and 1-3/4 in. long with a rear adjusting screw. It is used on metal framed patio doors.

Will the 1 in. steel ball bearing wheel run smoothly in my existing metal patio door track?

How do I confirm the rear adjustment screw is set correctly after fitting?

The housing is drawn against the side stile as the screw is tightened. Check that the roller moves freely and the door slides smoothly along the track.
