The GIBRALTAR TE1-2A-G is a square tube end fitting designed to cap and finish 1.5-inch square structural tubing. It accepts a 3/8-16 threaded fastener and is rated for a load capacity of 1,000 pounds. The 0.065-inch tube wall compatibility makes it suited for standard light-gauge square tube stock. This fitting is typically installed by fabricators, maintenance technicians, and structural assembly crews working with square tube frameworks, supports, and equipment stands.
This tube end is used in light structural and industrial fabrication applications where a finished, load-bearing end cap is required on 1.5-inch square tubing. Common install scenarios include equipment frames, safety rails, support stands, and similar assemblies that require a secure threaded end connection. It is a single-piece component supplied one unit per package.
Designed for use with 1.5-inch square structural tubing with a 0.065-inch wall thickness and a 3/8-16 thread fastener requirement.
Installation is performed by fabricators or maintenance technicians using standard hand tools. Ensure the tube end is fully seated and flush with the tube face before fastening. Verify that the mating tube wall thickness matches the 0.065-inch specification before install. Follow applicable structural assembly standards for your application.
