GN 1420 telescopic slides are installed in pairs. The stroke reaches ≈ 100 % of the nominal length l1 (full extension). The rubber stops dampen the impact of the slide in the two end positions and take on the locking function in the retracted position. This feature is noticeable through a slight resistance on opening and closing. If larger static or dynamic loads occur in the direction of extension, they should be absorbed by additional end stops.
The telescopic slides are delivered in pairs. They can be installed on either the left or right side due to the design. All mounting holes are easy to reach through auxiliary holes. Only the mounting holes are shown, but other production-related holes may be present.

For the listed loading forces FS to be absorbed reliably in the surrounding structure, all available countersunk holes of the outer and inner slide must be used. Failure to use mounting screws reduces the specified load capacity accordingly. The following screws can be used for mounting: |

|
Designation - Standard |
Outer slide Size 5 |
Inner slide Size 4 / 4.5 |
|||||||||
|
The maximum load capacity of telescopic slides depends on the slide cross-section and the nominal length l1 as well as the resulting stroke l2. Furthermore, the extension width, the slide materials used and the components of the equipment options, such as the dampened self-retracting mechanism, have a corresponding influence. |
