Hello there. There should have been an installation screw in the frame that the original rollers attached to. You would simply place the new rollers so that they could be-attached at these installation holes. Be sure to place the door on a flat, stable surface when doing this work. Let me know if this helps; if you have trouble still, let us know exactly how and we'll investigate for you. |
