I have a aluminium framed John Carr patio door fitted with plastic rollers that had started to break up. After much searching, these looked identical bar that the rollers looked a little bigger, they were. Although the rollers were slightly larger (about 5mm), the fitting was exactly the same, the only problem I had, if you can call it a problem is that there was very little room to get the door back in due to the extra height, but I managed! Quality product and extra quality service by DG Supplyline Ltd, especially after a cock up by me! Thanks again Rob and staff.
