3 3/8 in x 100 ft Strait-Flex Arch-Flex


Arch-Flex is designed for compound arches and double curve applications, including arched windows and doors, ceilings, soffits, staircases, barrel vaults, groin cathedrals; even taping around circular ducts.

Tear strips allow for straight-to-curve transitions in tight radiuses where conventional tapes show dents, paint chipping, shrinking and cracking problems. Apply with all-purpose joint-compound.

  • Arched windows and doors, tight radius curves, and free-form curves

  • Installs using standard compounds. No special tools or fasteners needed
  • Taping around circular air ducts
  • Produces smooth, professional-looking curves. Tear strips allow for easy straight-to-curve transitions
