The DANCO COMPANY 12399 is a pack of three flexible shims designed to level and stabilize plumbing fixtures, toilets, appliances, and other trade installations where a firm, even base is required. Flexible shims conform to uneven surfaces without cracking or splitting, allowing for precise adjustments during installation. Each pack includes three shims, giving the installer enough material to handle standard leveling tasks in a single service call. This product is commonly specified by plumbers and general trade contractors working on residential and light commercial projects.
Flexible shims are used wherever a fixture or appliance must be leveled on an uneven floor or mounting surface. Common applications include toilet base stabilization, washing machine leveling, cabinet shimming, and door or window frame adjustments during rough-in or finish work. The flexible construction makes them well suited for tile, vinyl, and other hard floor surfaces where rigid shims may rock or slip.
Designed as a general-purpose leveling accessory for use with toilets, plumbing fixtures, appliances, and cabinetry in residential and light commercial installations.
Flexible shims are typically installed by plumbers or general contractors during fixture set or appliance placement. Before shimming a toilet or plumbing fixture, shut off the water supply and ensure the floor surface is clean and dry. Slide shims into position at the base of the fixture and trim any excess material flush with the fixture edge using a utility knife. Follow all applicable local plumbing codes, including IPC guidelines, for fixture installation and stability requirements.
