DC450

Floor spring with Cam-Motion® technology for single and double action doors, size 3/4

The DC450 with fixed closing force is suitable for shallow applications. Balancing building design and accessibility, ASSA ABLOY floor springs are minimal on the outside and powerful on the inside – ideal for double action doors made of any material, even glass. The rapidly decreasing opening force of Cam-Motion technology ensures doors open with less effort.

  • Certified in compliance with EN 1154, size 3 or 4
  • Suitable for fire and smoke protection doors (not for hold-open variants)
  • For single and double action doors up to 1100 mm width and 120 kg weight
  • Barrier-free according to CEN/TR 15894
