HIBUMFX 3-Way Guy Wire Ring Clamp for 2-1/4" Mast

HIBUMFX adjustable 3-way guy wire ring is a heavy-duty galvanized steel clamp that secures antenna and mast systems up to 2-1/4" with three screw-eye attachment points.

This compact, easy-to-fit guy wire ring is designed for stabilizing vertical masts and antenna poles in demanding outdoor conditions. The zinc-galvanized steel construction resists corrosion, while the adjustable eyebolts and split-ring design let you fit a range of mast diameters and route three guy wires for stable, all-around support. It ships with the ring assembly and three screw-eye bolts ready for immediate installation.

How does the adjustable ring fit different mast sizes?

The split-ring clamp lets you loosen or remove the side bolts to expand the circumference so you can accept larger masts. Standard configuration fits smaller masts, and expanding the ring accommodates up to a 2-1/4" diameter mast. Adjustment is tool-driven and reversible for seasonal or site changes.

• Loosen side bolts to expand ring up to 2-1/4" (57 mm)
• Back out central bolts to fit masts as small as 1-1/4" (32 mm)
• Re-tighten for a secure, vibration-resistant clamp

What attachment points and hardware does it provide?

Each ring includes three screw-eye bolts spaced evenly to accept guy wires for a 120° spread, giving balanced lateral support. The screw-eyes are intended for direct connection of guy wire, thimbles, or turnbuckles depending on the rigging setup. This keeps the anchor points well-distributed around the mast.

• Three screw-eyes for 3-way guy wire attachment
• Even spacing promotes balanced load distribution
• Compatible with wire, thimbles, and turnbuckles for tensioning

How durable is the HIBUMFX guy wire ring outdoors?

Constructed from heavy-gauge steel and finished with zinc galvanization, the ring is built to withstand outdoor exposure and typical weather cycles. Galvanized coating reduces rusting at contact and exposed surfaces, extending service life compared to plain steel. For coastal or highly corrosive environments, routine inspections and additional protective measures are recommended.

• Heavy-duty steel core for mechanical strength
• Zinc galvanised finish resists surface corrosion
• Compact, low-profile design reduces wind catch

How easy is installation and maintenance?

Installation requires basic hand tools: a wrench to loosen and tighten the clamp bolts and a screwdriver or pliers for the screw-eyes. The split-ring concept simplifies placement around an existing mast without disassembly of the upper structure. Periodic checks of bolt tightness and eyelet condition keep the assembly secure.

• Fits around installed masts—no full disassembly needed
• Basic hand tools are sufficient for mounting
• Inspect bolts and eyelets seasonally for best performance

Who is this for: The HIBUMFX Adjustable 3-Way Guy Wire Ring is suited to installers, radio and antenna hobbyists, and contractors who need a robust, adjustable attachment point for guy wires on antenna masts up to 2-1/4". It’s ideal for repairs, upgrades, or new installations where a compact, corrosion-resistant clamp with three evenly spaced eyelets is required. Choose this ring when you want a straightforward, reusable solution for stabilizing vertical masts and antenna poles without complex fabrication or bespoke hardware.
