OP-DRG-25x100xR100 Cable Drag Chain
Plastic cable drag chain, 25 mm high x 100 mm wide, 100 mm bending radius, 1000 mm length.
Overview
The OP-DRG-25x100xR100 is a plastic cable drag chain for routing motor, encoder and sensor cables alongside a moving axis without them dragging on the machine bed or tangling on themselves.
Its cross-section is 25 mm high by 100 mm wide, wide enough to carry several cables side by side. The 100 mm bending radius sets how tight a loop the chain can fold into as the axis travels - too small a radius for the cables it carries can pinch or fatigue them over repeated cycles, so the radius should be chosen for the stiffest cable in the bundle, not the average.
It is supplied in a 1000 mm length and can be cut to size, in black plastic marked with colour dots for identifying chain segments during assembly.
Open-link construction lets cables be laid in from the side rather than threaded end to end, which matters when a cable already has connectors on both ends.
For a narrower bundle, the OP-DRG-25x50xR100 carries the same 25 mm height in a 50 mm width.
Supplied by Tiny Controls in India.

Questions
Does this come with end connectors built in, like the smaller OP-DRG chains do?
That's not stated for this size — unlike the OP-DRG-10x10 and 7x7 chains, this listing doesn't mention end connectors being included, so don't assume they are.
My cables already have connectors on both ends — can I still get them into a closed chain like this?
Yes — that's exactly what the open-link construction is for. Cables lay in from the side rather than needing to be threaded through end to end.
How do I know if the 100mm bend radius is actually tight enough for my cable bundle?
Size it to the stiffest cable in the bundle, not the average — too small a radius for that cable can pinch or fatigue it over repeated cycles.
Can I cut this down to a shorter length for my machine?
Yes — it's supplied in a 1000mm length and can be cut to size.
