CertainTeed Ceilings Drywall Suspension System main runners feature slots 8-inches on center. Each slot has two additional offset slots; each is 1-3/4-inches from the center slot. These additional offset slots allow for integration with Type F fixtures. Use the center slot for typical cross tee installation.

1 Install from below the grid

2 Fixture has integral flange (or separate flange kit) to finish the drywall board

3 Fixture rests on bulb of grid and/or is suspended from flange kit

4 Fixture is level with drywall

5 Requires actual 48-inch opening

1 Install from above the grid

2 Fixture trim is required for finishing drywall

Type F vs. Type G Fixtures

Type G Fixtures



48-inch, 50-inch and 72-inch On Center Spacing

Type F fixtures, air diffusers and access hatches require actual 12-inch, 24-inch and 48-inch openings in the suspension system. Type F fixtures can be installed both parallel and perpendicular to the main runners using 48-inch, 50-inch or 72-inch cross tees. The additional slots in the main runners and cross tees allow for integration with type F fixtures, while the availability of seven different cross tee sizes allows for framing without cutting and field modifications.

The combination of CertainTeed Ceilings offset main runner slots and availability of 48-inch, 50-inch and 72-inch cross tees allows for type F fixture installations on 48-inch, 50-inch and 72-inch centers.

There are a multitude of fixture placement options when installing type F fixtures 72-inches on center and perpendicular to the main runners. Cut the clips off the 26-inch cross tee and use the CertainTeed L-bracket (LBRC) to fasten the tee in place.

Type G fixtures can also be installed by cutting cross tee clips and using the LRBC to create the module size required instead of 15/16-inches wide face tees.

Installing the QuickSpan™ Locking Channel

1. Establish the ceiling level and drywall board thickness to be used.

2. Place the bottom of the QuickSpan Locking Channel (QSLC) at the appropriate level.

3. Decide upon a location for your first QuickSpan™ tee. The locking tabs on the QSLC are spaced every 8-inches on center and can be cut to the desired spacing from the abutting wall.

a. To cut the QSLC, choose the desired slot, measure from the wall and cut through the top and bottom flanges first. Finish by folding the scored piece back and cut through the rest of the channel.

4. Attach the QSLC with the appropriate fasteners. Use number 8, 1-1/4-inches long (32 mm), steel-framing, self-drilling tapping screws complying with SAE J78 and ASTM C1002.

5. On short walls where locking channel and/or tees are NOT needed; drywall wall angle can be used.

a. 1-1/2-inches (DWA1.5-1.5) or 2-inches (DWA2-2) wide pieces available

Installing the QuickSpan™ Tees

1. Measure across the hallway from inside of QSLC to inside of QSLC. Find a measurement that provides no more than a 1/4 inch gap and no less than a 1/8 inch gap between the insides of the channel.

a. For example, if the walls are 8-feet (96-inches) apart, you will want to cut your tees to 95-3/4 inches to allow the proper gap between the wall channel and tee. You can use a hot saw, band saw or tin snips to cut the cross tees down to size.

2. Start at one end of the ceiling and place a QuickSpan tee into the QSLC on both sides. Make sure that the tee is lying at an angle and moves freely in the channel.

a. Place all of the tees into the channel or do one at a time, it does not matter to the system.

3. Find the next slot on the QSLC that corresponds to the chosen spacing pattern and place the bulb (top) of the tee into the upper locator slot in the V of the QSLC.

4. Rotate the bottom of the tee into position. You will hear an audible click as the tee engages in the bottom locking tab of the QSLC. This will tell you that the tee is in place and locked.

a. Extra screws are NOT required, but a pilot hole is provided in the event that you find it necessary to apply a screw.

5. Proceed to the other end of the QuickSpan tee and follow the same process. Notice that the QuickSpan tee is snapped in the locking tabs on alternate sides of the QSLC. The system is designed this way to provide added rotational strength.

6. Note that there are hanger hole groupings provided every 8 inches across the tees. This allows the installer to provide a hanger where an excessive load is going to be placed on the system.

7. In the event that you want to create an opening for a device, simply cut a QuickSpan tee and screw it to the other tees in the appropriate location. a. Standard accessories are available to attach cross tees for device openings (L-Bracket LBRC,

Splice Clip DWSP and Direct Fixing Bracket DFB)

Installation Method and Instructions for QuickSpan™

Step-by-step illustrations - Assembly of Spanning Tee and Locking Channel



Installing Gypsum Board to the QuickSpan™ System

In non-fire rated ceiling assemblies, it is the contractor's discretion as to the orientation of the gypsum board, whether it is applied parallel or perpendicular to the supporting structure. The long, tapered edges of the board should be installed parallel to the QuickSpan tees. Some gypsum product manufacturers will require their product to be installed with the long, tapered edges perpendicular to ceiling framing members. Refer to their product data pages for specific information concerning product installation.

Maximum 5/8-inch thick gypsum board must be installed and fastened to the QuickSpan Locking Drywall System in accordance with IBC Section2508, ASTM C840, and Gypsum Association GA-216.

Change in Direction, Intersections, Bump-Outs and Coves

Change in Direction / Intersections 1. Apply a cross tee to the area just before the intersection or corner, making sure to completely engage both

wall channels.

2. Install a channel onto the adjacent wall, making sure to locate the locking tabs where they will function best.

3. Lock a tee into the new channel in the new corridor and set it on the flange of the last tee in the first corridor. Adjust the tee until it is square with the first corridor and screw the tees together or use an L-bracket (LBRC) to connect them.

4. Cut a piece of channel at a locking tab location and set that channel against the new cross tee. Fasten the tee to the wall and continue.

Coves / Recesses 1. When the ceiling condition includes a cove or recess in the hallway, span the channel across the opening and

continue along the wall.

2. Fasten the channel to the wall and cut the channel at the first available locking slot. This will allow use of QuickSpan as a guide for placing the channel in the correct position against the back wall of the cove or recess.

3. After the channel is installed along the long walls, either install the QuickSpan locking channel along the short walls or use Certainteed 1-1/2 inch or 2 inch drywall wall angle along the short walls.

Bump-Out / Columns 1. If the condition is a bump-out or column application, cut the locking channel into the obstruction.

2. To continue onto the outer face of the column or bump out, cut a channel at any upper locking slot and butt the channel up to the last tee before the column. This again will provide the proper module size down the wall.

3. Install the channel past the opposing corner of the bump out and cut it at the first available locking slot.

As with the cove condition, use the last tee as a guide for placing the channel against the back wall of the corridor. Apply drywall wall angle where applicable along the short edges to secure the board.
