Bottom-Mount Self-Closing Drawer Slides
The Prime-Line R 7212 kit provides 19-3/4 in. white powder-coated steel tracks with plastic rollers for bottom-mount drawer systems. Designed for cabinets with or without face frames, the slides require 1/2 in. side clearance and support a maximum load of 75 lbs. Installation instructions are included.
Sustained Load Behaviour
The self-closing mechanism activates during the final 2-1/2 in. of travel, pulling the drawer shut consistently over repeated cycles. Fixed tracks with a positive stop prevent over-extension, while the 11/16 in. diameter rear rollers stay fastened to the drawer-mounted pieces to maintain alignment under the rated 75 lbs. capacity.
Build Quality and Mounting Implications
White powder-coated steel resists corrosion in daily kitchen or workshop use. The kit cannot be cut to shorter depths because the rear rollers are fixed to the track ends. For face-frame cabinets with damaged back plates, the separate Prime-Line R 7240 part may be required to complete the installation.

Questions about this item
How much heat or noise do the 19-3/4 in. steel slides generate when a drawer stays open all day?
The slides are passive steel tracks with plastic rollers; they produce no heat and no audible noise while the drawer remains stationary.
What mounting hardware must I already have to install these bottom-mount slides?
You need a drawer and cabinet opening that provide 1/2 in. side clearance, 1/4 in. bottom clearance and 5/8 in. top clearance, plus screws for the included installation holes.
Will the self-closing action still engage if I keep my existing 11/16 in. rear rollers?
The self-close mechanism activates in the final 2-1/2 in. of travel and works with the supplied rollers; reusing older rollers is not addressed in the installation guide.
