Product Information
The Tusa M-21, 30, 40, TM-6000Q Mask Strap (TUSA part number TC-105) is a replacement mask strap made for the TUSA M-21, M-30, M-40 and TM-6000Q dive masks, giving divers a way to restore the strap on these masks without buying an entirely new mask.
Who it is for
This strap is for divers who already own a TUSA M-21, M-30, M-40 or TM-6000Q mask and need a replacement strap, whether the original has stretched out, cracked, or been lost. It is a simple way to keep a mask you already know fits you well in service, dive after dive, instead of replacing the whole mask over a worn strap.
