Balsa Truss Tester

A strong truss makes a strong bridge or roof. So testing a truss design before building an entire model bridge or roof makes sense – and now you can do that with the Balsa Truss Tester. It works with either a hanging weight or on the Structures Testing Instrument, sold separately. Designed specifically for trusses made from 1/8" balsa wood, this tester adjusts for trusses up to 4" tall and 12" wide. It has two different load blocks: one adjusts to four different angles (15°, 20°, 25°, and 30°) for triangular trusses, and the other is square for flat-topped trusses. The tester’s clear acrylic shield keeps trusses securely in place for testing while offering protection from splintering wood. Comes assembled.
