TMS Silent Clips - A237R

Installation Instructions

Installation Notes:

● A237R clips shall not exceed 48” on center

● Spacing between hat channels shall not exceed 24”

● Fasten the A237R clips to the substrate with a fastener approved for a minimum pull-out and shear of 120 Lbs.

● Locate the bottom row of A237R clips within 3” of the floor. (May be adjusted lower to accommodate installation of baseboard)

● Hat Channels are installed horizontal to the floor.

● Use a 4' level to ensure that A237R clips and furring channels are installed horizontal and level.

● Install the drywall vertically from the bottom up leaving a 1/4” thick gap around perimeter of wall to be filled with acoustical caulk. Caulk around the entire perimeter of the gypsum board.

Step 1:Review layout guidelines before starting installation of walls or ceilings (see Page 6). We suggest installing the ceiling first, before installing the walls.

Step 2:Space A237R clips so not to exceed 48” OC. Secure clips with a single fastener through the middle screw hole in the clip (Fig 2.1).

FOR FIRE RATED APPLICATIONS SEE PAGE 4 FOR INSTALLATION INSTRUCTIONS

Wood: Use #8 x 2-1/2” coarse thread screwsSteel: Use #8, #10 or #12 x 1- 5/8 Type s Self tapping screwsConcrete: Use 3.16” x 2 1/4” Tapcon or equal anchor

Step 3:Snap hat channel on A237R clips (Fig 2.2)

Step 4:

The Floor Shims are critical to ensure best results. Place 1/4” shims on floor in front of sole plate (Fig 3.1). Install the first row of drywall vertically against the wall (Fig. 3.2). Attach drywall to channel following local building codes.

Note: Only remove the shims after all the gypsum board is completely screwed to all furring channels.

Step 5:

Use acoustical caulk around the entire perimeter of each wall (See Figure 3.3)

Load Specification for A237R Clip:

A237R Clips are designed to carry furring channel with one or more layers of gypsum wallboard attached. The load capacity of the clips depends on the gauge of the hat channel used.

25 Gauge furring channel carries less load that 22 Gauge channel but performs better acoustically. The maximum design load capacity for theA237R clips in shear ( Wall Application) or in tension (Ceiling Applications) as follows. Design load calculations are based on testing loading to failure where the furring channel deforms.

Maximum Load for Wall and Ceiling

2:1 safety factor 2.5:1 safety factor*

Resilmount Clips w/ 25 gauge hat channel

45 lbs 36 lbs

Resilmount Clips w/ 22 gauge hat channel

60 lbs 48 lbs

* Suggested safety factor 2.5:1 for more critical life safety applications

Note: 5/8” thick gypsum wallboard weighs w.3 lbs/sq ft.

1/2” thick gypsum wallboard weighs 1.85 lbs/sq ft.
