Tandem Steel Roller Assembly for Sliding Patio Doors
This discontinued tandem roller assembly was originally manufactured by Ultra and rides on tough 1-1/4 inch steel ball-bearing wheels. As a trusted dealer of sliding glass patio door rollers, PatioDoorParts.com offers this replacement, which may require minor modification to install.
This roller was used by Metal Industries, Capitol, and other manufacturers. The .680 or .720 inch housing width is measured at the rivets. A suggested replacement option is item 13092, which features a 3/4 inch housing with a 1-1/4 inch diameter steel wheel. Note C-2 is the adjustment range for the roller assembly; with the 1-1/4 inch wheel, the replacement would adjust from 1.29 to 1.74 inches. The Ultra C2 roller assembly is replaced with our 13092 dual roller. To install: remove the bottom rail, remove the old roller, then position the new roller in about the same place. The new roller has a hole in the top for a 10-32 screw and a 1/4-20 end screw; mark where the top hole will fall on the rail and remove the roller. Drill a hole through the bottom rail to attach the 10-32 truss screw into the new roller assembly, then insert the new roller and secure it with a 10-32 low profile screw or countersink. The adjusting screw and 1/4-20 frame screws have changed position, with the adjusting screw now at the bottom, so it may be necessary to enlarge the hole to access the adjustment screw.

How to confirm fit
Wheel diameter is the size of the round wheel across its center. Measure the wheel only, not the metal housing.
Measure this
Across the center, outer edge to outer edge. Ignore the housing, axle heads, rivets, and adjustment screw.
- Retract the rollers and remove the door panel if needed.
- Slide the roller assembly out of the rail.
- Find a less-worn spot on the wheel (flat spots read small).
- Measure through the center with a ruler or calipers.
- For tandem, measure one wheel only. Do not add both together.
Edge tip: Flat has a smooth rim. Concave / grooved has a U or V in the middle.
Open full wheel guideHousing width is the metal cassette size side to side. It is the key fit dimension for most patio door rollers.
Measure this
Metal housing side to side where the cassette fits the door pocket. Ignore the wheel, tabs, and overall length.
- Retract the rollers and remove the panel if needed.
- Slide the metal housing out of the bottom rail.
- Look at the narrow side of the housing, not the wheel face.
- Measure side plate to side plate across the main metal body.
- Ignore lips, tabs, and flanges that stick out.
Do not use: wheel diameter, tab length, or the rail opening as housing width.
Open full housing guideTab style is the back mounting shape. Match the tab first, then confirm diameter and housing in the Roller Finder.
How to inspect
- Lift or tip the door panel enough to reach the bottom rollers.
- Loosen the adjustment screw and slide the housing out.
- Hold the housing so you can see the back clearly.
- Compare the mounting shape to the tab photos on the identify page.
- Photograph the back straight on, plus one side view, before you order.
Tab style is independent of wheel diameter and material.
