T-Lock is a tile leveling system used for large format tiles (edges greater than 15" long). This system helps tile setters get level wall or floor tiles and reduce call backs from clients. Wedges and clips are used to to avoid tile lippage. Wedges are reusable, save the contractor money, and can be installed by hand. Clips have spacers (1/32",1/16", and 1/8") integrated into the design. For more information visit our store https://shop.bathroomrepairtutor.com/
