On which end cap of the type DGP/L drive are the supply ports located as standard?
The two sizes 8 and 12 are only available with a supply port in each end cap. With sizes 18 and higher, both supply ports are located on one side (exception: variant “D2” which has a supply port on each side). In the standard design, the air supply ports are in the right-hand end cap (runner upwards and slide unit to the rear – see illustration).
