RSIC-DC04 - Resilient Sound Isolation Clips

RSIC-DC04 is our most versatile RSIC clip. It works with 25 gauge hat channel with a hemmed edge detail run vertically. It also fits low-profile walls as shallow as 1/2", ceiling fan blocking, and wire-hung drywall grid ceilings. It fastens to wood, steel, and concrete. It also isolates garage door motors and rails, vent fans, speakers, projector mounts, and electrical boxes.

RSIC-DC04 is the pick for vertical channel, low-profile walls, ceiling fan blocking, and wire-hung ceilings. The 25 gauge hat channel with a hemmed edge detail screws into RSIC-DC04, while it snaps into RSIC-1. Because the channel is screwed, it cannot slide down when it runs vertically. RSIC-1 remains our standard clip for new walls and ceilings.

Yes, you can install a ceiling fan on an isolated ceiling by isolating the blocking between the joists with RSIC-DC04 clips. A single clip holds 144 lbs in this setup. Two clips used together hold 288 lbs.

RSIC-DC04 is best for ceiling drops of about 6" to 12" from a concrete slab, hung from wire. For shallower drops of 2-5/8" to 6", see RSIC-1 ADM. For drops of 12"+, see RSIC-WHI.

At 24" x 48" o.c., plan on about 1 clip for every 5 sq ft of ceiling. That spacing supports up to 2 layers of 5/8" drywall. For 1 layer of 5/8" Type C drywall, you can space the clips up to 48" x 48" o.c. Call us at 1-800-679-8511 for an exact clip count for your ceiling.

Yes, you can run 25 gauge hat channel with a hemmed edge detail vertically, parallel to the studs, with RSIC-DC04. The channel screws to the clips instead of snapping in. That keeps it from sliding down.

Fasten the clips to the framing at up to 48" x 48" o.c. Screw the 25 gauge hat channel with a hemmed edge detail to the clips. Screw 5/8" drywall to the channel, leaving a 1/4" gap around the perimeter. Seal that gap and any penetrations with acoustical sealant. The RSIC-DC04 install guide covers fasteners and spacing.

Fasten the clips to the concrete or framing at 48" x 48" o.c. or closer, with the first and last rows within 8" of the wall. Tie annealed hanger wire, 12 gauge minimum, through the 1/4" hole in each clip's vertical leg. Hang the drywall grid ceiling following the grid manufacturer's instructions. Seal the perimeter and any penetrations with acoustical sealant. The install guide shows the layouts.

For a wall, you need RSIC-DC04 clips, 25 gauge hat channel, screws or anchors, 5/8" drywall, and acoustical sealant. For a wire-hung ceiling, you need 12 gauge minimum annealed hanger wire in place of the channel. Never fasten the clips with nails. The table lists the right fastener for each setup, and the install guide has the details.

Yes, RSIC-DC04 clips are assembled in the USA.
