The roller assembly (1), for a sliding door, rides in a guide rail (17) with a stop and retaining unit (21). A buffer (33) acts as the end limit stop, with a brake to act on the sliding door before reaching the end limit stop and a retainer (37) to hold the door at the end position. The stop and retaining unit slides in the rail to be locked in the required position. The buffer and retainer can be fitted selectively to either side of the stop and retaining unit. |
