HKD 74HF hollow wall combination box, 74 mm, halogen-free The halogen-free HKD 74HF hollow wall combination box can be used as a single box or a combination box, which ensures a distance of 71 mm and guarantees compact installation. The increased wiring space gives the inserts more freedom of movement in multiple combinations. The crosshairs and the grain points on the bottom of the box guarantee quick and precise assembly of a multiple combination. 4 side entries for hoses, 4-way, screw fastening option for support rings offset by 90°. Direct cable feed-through in multiple combinations possible thanks to the easily breakable connecting bridge. The hole diameter of 74 mm makes it easier to remove the hoses from the partition wall. Fastening screws 3 x 15 mm included. Depth 53 mm, for panel thickness 6 to 30 mm. A conventional hole drill with a diameter of 74 mm is required (with or without countersink), e.g. item no. 999807.
