The 2820-060 wood shear fixture is designed for testing shear strength properties of wood or adhesive bonds in wood by compression loading. The fixture consists of a high-strength steel body with a sliding , self-aligning anvil which is used to apply compressive loading to the specimen in shear. The shear line can be set at 0.0 mm, 2.0 mm or 3.0 mm by using shims. The shims are clearly engraved with the applicable standard and are easy and quick to change. The fixture is attached to the test system using simple clevis pin interfaces which allow quick and easy fitting and removal.
