Thank you for viewing. These are low rails for sliding doors that I bought a few years ago because the drawer broke. The size was wrong, so they've been sitting unused. They are new and unused, one bag unopened and one bag opened but unused. I am selling two sets, for a total of two bags. (This is equivalent to two shelves in a drawer.) 【Product Description】 The most common roller structure for attaching to the bottom of a drawer! Perfect for keyboard trays, etc.! Detachable, one-way slide ・ 350mm WS3835 ・・Size: 350mm ・Material: Steel (powder coating finish) ・Load capacity: 20kg (pair, left and right) ・Clearance: 12.5mm ・Sliding distance: 269mm ・Remaining length: 81mm ⚠ Note: Mounting screws are not included.
