This United Plastics extrusion is a grooved-type rubber retainer for holding glass and panel inserts in a frame, supplied on a 500 foot roll.
Glazed cabinet doors need something to keep the glass in the frame cleanly, without a visible stop or an exposed fastener from the front. Grooved retainer does it by seating into a groove machined around the frame opening: the strip goes in behind the glass, the groove grips the strip, and nothing shows. That clean hold is the reason to choose this type, and it is also the requirement: the frame has to be machined for a groove before this retainer can do its job. Frames without a machined groove call for the stapled type instead. The two are not interchangeable.
Black is the practical default for painted frames and for stained frames in darker tones, where the retainer line is meant to read as a shadow rather than stand out. On a grooved installation the strip sits behind the glass and most of it is hidden, so color matters less than it does on a stapled installation where the strip is more visible. Still, matching the frame tone removes any chance of a contrast line showing at the edge of the glass.
The 500 foot roll is the volume option in this range. A cabinet shop running glazed doors as a regular part of production will exhaust a 100 foot roll quickly; the 500 foot roll reduces how often the shop has to reorder and keeps the job moving. It is a straight arithmetic decision: five times the footage at the larger roll size.
Grooved retainer seats into a machined groove in the frame and is held by the groove itself. Stapled retainer is fastened through the strip. They are made for different frame constructions and cannot substitute for each other.
No. This is the grooved type, which requires a machined groove to seat in. For frames without a groove, the stapled type is the correct product.
Profile dimension and groove size are not specified in the available product data. Confirm the cross-section against your frame's groove before ordering.
500 feet.
For a shop glazing cabinet doors on a regular schedule, the 500 foot roll keeps retainer on hand and the line moving, in a black that disappears against dark and painted frames.
