These are our top-of-the-line European bottom-mount drawer slides, finished in white or brown epoxy. The right-hand slide has a captive roller to eliminate lateral movement.
Side clearance is 1/2" ±1/32", and slide height is 1 19/64". Load rated for 100 lb, they operate smoothly, and are self-closing in the last inch or so of travel. Overall extension loss ranges from 3" to 4" of total slide length.
Made in Austria, these have a lifetime warranty against failure in consumer use.
Priced per pair; mounting screws included.
