Mounting the D-R..L rail, clamping piece and rail extension
– D-R..L rails are available in 50, 100, 150, 200 and 230 cm lengths.
– Use the D-CP-M/L clamping piece, item no. 207137/1, when the rail is mounted vertically. Attach the clamp-
ing piece to the D-R..L rail and hook it into the upper, previously aligned and levelled DS-RF rail support.
– Position the lower end of the rail in the lower rail support (not yet fully tightened), slide up the clamping plate
and tighten the M12 screw. Check the distance from the cutting line and alignment of the rail before fully
tightening the screw.
– When mounting the rails, always position the rail support at right angles to the rail and then tighten all rail fas-
tening screws securely.
– All Hilti D-R..L rails can be extended to form a rigid unit by making use of a tapered connector: D-C-O-ML
double taper, item no. 232241/0, eccentric pin, item no. 231244/4.
– The recommended distance between rail supports is approx. 1.5 m.
– When a double taper is not available for use, rails can be extended by mounting a rail support at the joint
between two rails. In this case, use an end stop to set the correct distance between rail sections.
– D-R..L rails are also used as the column in the DD-750 HY hydraulic drilling system.
