Product Description

Wobble Wedges are a modular system of precision engineered, securely stackable, non-slip, tapered plastic shims. They are available in four interlocking and cross-nesting sizes, in both soft and hard resins. Wobble Wedges can be used independently or can be stacked in any combination or orientation to accomplish practically any shimming need.


They are typically used by industrial manufacturers, restaurants and food service suppliers, plumbing contractors, woodworkers, cabinet and closet installers, hobbyists and do-it-yourself homemakers to stabilize, support, level or protect workpieces, restaurant tables, furniture, cabinets, shelving, appliances, HVAC equipment, aluminum sheets and other similar items. Hard Wobble Wedges provide firm support for heavy objects. Soft Wobble Wedges absorb vibration and silence rattles.

Wobble Wedges are also commonly used as a highly adaptable tool. Learn more >

Patented System

The Wobble Wedges modular system is patented and has no equal. Each wedge in the system is comprised of multiple rows and off-set columns of ridges that provide precise, repeatable adjustments, secure stackability and both lateral and horizontal stability.

Standard Wobble Wedges have 5 columns and 32 rows of deep off-set ridges on both sides of the wedge. Under load, these deep off-set ridges oppose each other at as many as 144 points which eliminates both horizontal and vertical slippage.
