Constructed with the patented tear away boot design the TuffBox is the way to go when installing a register box.

TuffBox is a heavy, 1-piece durable polymer shell. Virtually air-tight molded design delivers 100% of air flow. Using an innovative stepped design supporting 3 duct sizes, collars are 1" & beaded to hold flexible duct in place while securing strap.

Features:

• Stepped collar for multiple duct sizes
• Collar tabs easily tear away unneeded sections - allow on-site adjustment & labor savings
• Mounting clip accommodates thicknesses up to 1-1/4"
• 5/8" standoffs provide correct depth to accommodate strapping/furring used with drywall
• Flange is flexible to conform to drywall backing, virtually eliminating leakage between grille and box
