Lap clamps provide and maintain proper track separation at the center overlap of bi-parting track systems so that the master carriers can operate properly in the overlap. The clamps are constructed of plated or powder coated formed steel and are provided with all assembly hardware. The Model 1407 clamps are used only with suspended track systems where the tracks are NOT curved through the overlap. If the tracks are curved through the overlap, lap clamp Model 1407-A MUST be used. Note: 2 required, sold individually. Approximately: 4" wide x 1-1/2" long x 3/8" deep.
