Closet Door Roller Assembly

The Prime-Line N 6659 is a nylon roller assembly designed for sliding closet doors. It supports a maximum door weight of 40 lb and includes two wheels with steel bearings. The unit measures 3-53/64 inches in length and 6-7/16 inches in height. Hardware is included for door mounting.

Suits standard sliding closet doors

This assembly fits doors requiring a 1-inch wheel diameter and a 7/8-inch roller width. The 1/4-inch inside diameter and 1-1/8-inch outside diameter match common hanger specifications. It is not suitable for doors exceeding the 40 lb weight limit or for pocket door systems needing a different roller profile. Buyers needing a larger wheel diameter should look elsewhere.

Verify your door hardware

Confirm your existing hanger uses a 3/16-inch mounting hole before ordering. The shaft length is 1-1/8 inches and the overall depth is 1-1/8 inches. Ensure the door thickness accommodates the 3-13/16-inch width. This unit requires separate hangers for installation.

Questions about this item

What door weight must the buyer already know before installing the Prime-Line N 6659 roller assembly?

The assembly supports a maximum door weight of 40 lb, so the existing closet door must not exceed that limit for safe operation.

How does the 1 in. wheel diameter work with an existing track that has a 1-1/8 in. maximum wheel diameter?

The 1 in. wheels fit within the 1-1/8 in. maximum wheel diameter, allowing the roller to run on tracks designed for that size without binding.

How can the buyer confirm the roller assembly is working as intended after setup?

The door should glide smoothly along the track, the two nylon wheels should rotate freely on their steel bearings, and the door must remain level while supporting up to 40 lb.
