The DTC DS10 Undermount Slide moves a 40kg (88 lbs) dynamic load smoothly and quietly while guaranteeing excellent soft-close performance. Included with a pair of slides is a 4-way adjustment front locking clip. These clips feature height adjustment of 0-3mm and lateral side adjustment of ±1.5mm. Your installers will appreciate the ease with which they can make your drawer fronts align. For inset drawers, we recommend switching to the optional 6-way adjustment clip, with the additional depth adjustment, enabling final drawer front alignment. DTC's DS10 Undermount Slide was tested in an independent labratory under ANSI/KCMA A161.1 - 2017 Section 7.1 Drawer Operation Tests to 40,000 cycles with a complete passing grade. The DS-10 slide was further tested by TUVRheinland (European standard) to 80,000 cycles, twice the US standard, receiving a complete passing grade.
