Detachable spindle
The spindle is available in seven different lengths and in two different variants to allow for flexible installation
DC477
Floor spring with Cam-Motion® technology for single and double action doors, size 2-4
The DC477 with adjustable closing force is suitable for heavy doors. Balancing building design and accessibility, ASSA ABLOY floor springs are minimal on the outside and powerful on the inside – ideal for large double action doors made of any material, even glass. The rapidly decreasing opening force of Cam-Motion technology ensures doors open with less effort.

- Suitable for fire and smoke protection doors (not for hold-open variants)
- For single and double action doors up to 1100 mm width and 170 kg weight
