Grove Shims™ Plastic Shim Manufacturing

grove shims made in the USA

Our 100% American-made plastic shims qualify under the Buy American Act. Each plastic shim is manufactured entirely in our facility in Leominster, MA where we apply stringent quality control. Leominster is known as the “Plastics City” because it helped give birth to the plastics industry. Starting with the invention of celluloid in 1868, Leominster became a center of plastics production and know-how. The evolution from primitive materials to modern plastics was pioneered here. That deep-rooted manufacturing tradition and expertise is in every shim we make. Grove Shims™ is able to deliver shims throughout the US within 48 hours (or sooner if your need is urgent).
