Rixson Shallow Depth

Floor closers provide the best mechanical means to support and control a door. They are designed to work with the laws of physics to provide long-lasting performance and reliability. Rixson^® shallow depth floor closers are recommended for low to moderate traffic interior doors, where traditional floor closer depth is too great for slab construction.

(Not recommended for high traffic or exterior doors)

Weight of door supported by bottom arm and floor:

Uses laws of gravity to its advantage
Door swings with less resistance
Reduced stress on frame
Fasteners are in shear, not tension
Eliminates door sag
Vertically adjustable
Thrust bearing supports vertical load
Needle bearings for lateral forces

Interchangeable spindle adapters:

Up to 2" longer than standard in 1/2" increments

Bottom arm directly attached to closer spindle:

A mechanical advantage that increases efficiency insuring that ICC/ANSI A117.1 compliant, lower opening forces will still close the door
One to one ratio of door swing to spindle rotation makes control more precise
Floor closers are more efficient than a regular arm surface closer

Advantages of concealed floor closers:

Aesthetics – let the beauty of the door and its surroundings take center stage
Vandal resistant – mechanism not exposed
The solution for arch top doors – offset floor closers
Both mechanical advantages and aesthetics – a concealed floor closer exclusive

Many different models to choose from:

Use standard product with a top pivot for the best efficiency
Use a quick install (Q) model to facilitate easy closer removal
Use model HM with 3/4" offset hinges for hollow metal doors and frames prepared for 4-1/2" hinges
