Ball-bearing partial extensions Accuride 2132. Guided by a ball cage, with adjustment notches for the drawer +/- 1.6 mm and an anti-rollback feature, divisible. Drawers can be detached from the guide using a release lever. The anti-rollback feature keeps the drawer securely in the closed position, with a 32 mm hole pattern. For optimal running properties: installation width + 0.2-0.5 mm. When mounted horizontally, the load capacity of the rail is reduced to 25%. The deflection of horizontally mounted rails varies depending on the application. We recommend building a prototype to determine if the deflection is within an acceptable range.
