KERDI-BAND 7-1/4" is the mid-width format — wider than the 5" but more manageable than the 10" for vertical wall seams and KERDI-BOARD panel joints. It's the right choice when you need a bit more lap coverage than the standard strip provides, but the 10" feels like overkill for the detail you're working on.

Same KERDI membrane material, embedded in thin-set over your seam or joint. Works with all KERDI and DITRA assemblies and KERDI-BOARD building panels.

Pro Tip: If you're ordering KERDI-BAND and aren't sure which width to get, here's a simple rule: 5" for standard roll-to-roll seams on walls, 7-1/4" for KERDI-BOARD panel joints and niche perifeet, 10" for floor-to-wall transitions. Getting the width right means one clean pass — fighting a too-narrow strip into a corner adds time and risk. Buy the right width the first time.
