For telescopic slides with partial extension, the travel is less than the overall length. They are an inexpensive solution for low friction rails of drawers or similar. The dynamic load capacity of the telescopic slides indicates the maximum load rating of a vertically mounted slide pair when the entire extension length is used. The specified load-bearing capacities refer to the maximum value at 100,000 cycles. The telescopic slides can be extended in both directions.

All telescopic rails are tested to DIN EN 15338.
