Universal Pole Bracket
- Adjustable multi-purpose bracket for non-standard or retrofit pole-mount applications
- Three sizes covering pole diameters 150–450 mm (6–18 inch)
- Hot-dip galvanized to ASTM A-123 (≥86 μm)
- Field-adjustable strap mechanism — no drilling required

Application & Installation
Where it is used
- Retrofit installations where drilling the pole is not permitted
- Concrete or composite poles where field drilling is difficult
- Temporary equipment mounts during construction or maintenance
- Telecom or utility-yard equipment that needs to be removed without leaving holes
- Non-standard pole geometries (octagonal, tapered, irregular) where a fixed-pattern bracket won’t fit
Installation sequence
- Open the strap mechanism and wrap it around the pole at the target elevation.
- Close the strap; verify it sits flat against the pole face.
- Tighten the strap tension bolt until the bracket cannot rotate by hand.
- Final torque: 60–80 ft-lb on the strap bolt; 30–50 ft-lb on the outboard equipment bolts.
- Verify the bracket is level and the outboard mounting plate faces the planned equipment direction.
Buyer’s Guide: Universal Pole Bracket
1. When Do You Need an Universal Pole Bracket?
A universal pole bracket is the go-to choice when you can’t (or don’t want to) drill the pole for a fixed-pattern bracket. The strap mechanism wraps around any pole 150–450 mm in diameter and tensions to grip the surface without piercing it — useful for retrofit installations, concrete or composite poles, and temporary equipment mounts. The outboard 4-hole mounting plate accepts standard M12 bolts for attaching whatever equipment the project needs (junction box, telecom enclosure, lighting fixture, etc.).
Working load is 100 kg per bracket — below the rating of a drilled-pattern bracket like the Crossarm Mounting Bracket, but sufficient for almost any equipment installation that doesn’t carry a primary structural load. For applications above 100 kg or where the bracket must hold an arm that itself carries conductor load, use a drilled-pattern bracket instead. The strap is self-locking once tensioned, but for high-vibration applications (poles adjacent to roadways or railroad tracks), specify a tamper-resistant locking nut at order time.
2. How to Choose the Right Size
Pick by pole diameter at the mount elevation.
- RAX-UPB-S — 150–250 mm poles, distribution
- RAX-UPB-M — 250–350 mm poles, heavy distribution / light transmission
- RAX-UPB-L — 350–450 mm poles, transmission and special structures
For poles outside this range (smaller than 150 mm or larger than 450 mm), specify custom strap length at order. 5–7 day tooling for non-standard sizes, 100-piece minimum.
