• Suspended drywall grid system eliminates the need for
hat track and carrying channel
• Simple stab and click installation eliminates labor-intensive
cutting and tying
• Drywall grid system installs in the same time it takes to
install an acoustical grid system
• ScrewStop feature offers more consistent, positive screw
attachment of gypsum board
• Manufactured rout locations eliminate the need to measure
and ensures consistent module spacing
• 51 main beam routs and 7 cross tees engineered to eliminate
time consuming field modifications for type “F” fixtures
• Maximize ceiling height with single layer framing — important
in low clearance installations

Example calculation based on 5,100 SF ceiling:
Main beam at 48″ O.C.
5,100 SF x .25 = 1,275 LF
1,275 LF ÷ 144 LF/Ctn = 9 cartons needed
Cross tee at 16″ O.C.
5,100 SF x .76 = 3,876 LF
3,876 LF ÷ 144 LF/Ctn = 27 cartons needed
