The SIOUX CHIEF sc-460-11300 is a stiff polypropylene closet shim designed for leveling and securing toilet bases during rough-in and finish plumbing installations. Part of the Wedge-It Series 460 line, this shim is molded from natural polypropylene for consistent rigidity and resistance to moisture, making it well suited to the wet environments common in bathroom rough-ins. The wedge profile allows plumbers to drive the shim under a toilet base to eliminate rocking and establish a stable, level seat before wax ring compression and bolt tightening. Each bag contains 10 shims, providing enough material for a full residential toilet installation with spares for adjustment.
This shim is used in residential and light commercial plumbing applications wherever a toilet or closet flange requires shimming to achieve a level base. Installers use these shims during new construction and remodel work to correct minor floor irregularities at the toilet footprint. The polypropylene construction handles continuous exposure to cleaning agents and standing water without degrading or losing shape over time. The 10-per-bag pack count is suited to single-fixture jobs or stocking a service van for repeat closet installations.
Designed as an OEM-style replacement and standard-use shim for residential and light commercial toilet base leveling applications at standard closet flange installations.
Installation is performed by licensed plumbers or experienced tradespeople during toilet rough-in or reset. Shut off the water supply and remove the toilet before shimming the base if resetting an existing fixture. Drive shims under the toilet base at the low points to eliminate rocking before final bolt torque and wax ring seating. Trim any exposed shim material flush with the base after the toilet is set and before applying caulk at the floor line per local plumbing code requirements.
