3 in x 100 ft Strait-Flex Mid-Flex 300


Designed for straightening common irregularities in vaulted ceilings and coffers.

Mid-Flex 300, a paper-faced, laminated composite corner tape from Strait-Flex, beautifully finishes outside corners, off angles, and vaulted ceilings. Mid-Flex 300 is also a great choice when replacing damaged metal corner bead. This 3” tape features a pre-finished surface with a PUR–laminated nose ensuring perfect corners without paper fuzz-up during finishing and sanding. The tape’s outer edge features a diamond punch pattern for a superior bond, faster drying, with no rippling or blistering. Highly recommended for corners in vaulted ceilings.

  • Off angles and outside 90º corners
  • Outside corners where a large fill or straightening is required
  • Outside corners of bay windows, coffers
  • Vaulted ceilings and butterfly vaults
  • Replacing damaged metal corner bead
