DC135 is the standard Assa Abloy surface-mount closer — the body that sits visible at the head of the door with an arm to the leaf. Cam-action geometry gives a low opening force at the start (easy to push) and full closing force at the end (positive latch every time), which is the right curve for residential and light commercial traffic. Sized for leaves up to 38 inches wide, EN 2–4 strength range, and fire-door certified up to 60 minutes — the closer we specify whenever the spec doesn't call for an invisible solution.
The cam profile delivers low opening force at the start and full closing force at the end — easy to push open, positive latch on close. The right curve for everyday residential and light commercial traffic.
Field-adjustable across EN 2, 3, and 4 power sizes. One closer body can be set on site to match the leaf width and any draft conditions in the corridor.
Tested to EN 1634-1 for FD60 (60-minute) fire-rated leaves. Specified on rated openings where the surface arm is acceptable from a design standpoint.
Standard residential and light commercial leaves up to 38 inch wide — corridor doors, garage-to-house doors, mechanical rooms. The default surface closer when the design accepts a visible arm.
