GBGS 2-Pack O.D.2 Swivel Jack Male Pipe Mount Plates — Bolt-On, Low-Carbon Steel Coated

These two GBGS male pipe mount plates convert O.D. 2" swivel jacks into secure, bolt-on trailer supports for RVs, campers, boat trailers and utility trailers.

Use this 2-pack of GBGS O.D.2 male pipe mount plates when you need a reliable bracket to bolt a 2-inch outer-diameter swivel jack to your trailer frame. Each plate is fabricated from low-carbon steel with a protective spray coating and pre-drilled holes sized for standard 5/8" pins and Φ14mm (for 1/2" bolts). The welded pipe socket and robust wall thickness provide a stable anchor that keeps the jack aligned and ready to raise or lower loads without wobble.

How do these plates fit my O.D. 2" swivel jack?

The socket is sized specifically for O.D. 2" pipe-mount swivel jacks so the jack’s male pipe slips into the mount for a snug, secure fit. Pre-drilled mounting holes let you bolt the plate to your trailer frame for a bolt-on installation rather than permanent welding.

• Socket designed for 2" outer-diameter pipe swivel jacks
• Pre-drilled hole for 5/8" retaining pin
• Φ14mm holes accommodate 1/2" bolts for frame attachment
• Welded plate ensures correct pipe alignment and durability

What are the build and finish details I should know about?

Each mount plate is manufactured from low-carbon steel with a welded 1/4" plate and a 3/16" wall pipe socket for strength where it matters. The spray coating provides surface protection against corrosion and everyday wear, making the mounts suitable for outdoor trailer use.

• Material: low-carbon steel for toughness
• Plate thickness: 1/4" welded plate; pipe wall: 3/16"
• Protective spray coating to resist rust and abrasion
• Compact plate size: 5" wide x 4-1/4" tall x 2" deep

How is installation handled and what tools are needed?

Installation is straightforward: position the plate on your trailer frame, align the Φ14mm bolt holes, and secure with 1/2" bolts or appropriate hardware. The 5/8" pin hole aligns the jack pipe so you can insert the retaining pin, allowing the jack to swivel and lock into place as required.

• Mounting requires drilling or matching existing frame holes to Φ14mm
• Use 1/2" bolts and nuts (grade and length per trailer specs)
• Secure jack with 5/8" pin through pre-drilled pin hole
• No welding required for bolt-on installation, though weld-in option remains possible

Will these mounts work for my trailer type and loads?

These plates are intended for general trailer and recreational applications—RVs, campers, boat trailers and utility trailers—paired with compatible O.D. 2" swivel jacks. They provide a stable mounting point for typical trailer tongue loads; choose bolts and hardware rated for your trailer’s weight and towing demands.

• Commonly used on RVs, campers, boat trailers and utility trailers
• Designed for standard 2" pipe swivel jacks, not specialized custom jacks
• Hardware selection should match your trailer’s load rating
• Two plates in the pack allow spares or multi-point installations

Who is this for: installers, DIY trailer owners and professional mechanics who need a sturdy, bolt-on mount for O.D. 2" swivel jacks. If you want a reliable male pipe socket with pre-drilled holes, welded construction and a protective finish for outdoor trailer use, the GBGS 2 Pack O.D.2 Swivel Jack Male Pipe Mount Plates offer a practical, ready-to-install solution.
