Application & Installation
Where it is used
- Distribution line angles & dead-ends with unbalanced conductor tension
- Heavy transformer mounting (15–50 kVA)
- Long-span construction (>250 ft) with heavier conductors
- Reinforced rural / agricultural lines per RUS 1728F-810
- Alley arm support where space permits a single-piece brace
Installation sequence
- Mark the pole 12–18 in below the crossarm at the planned mount point.
- Through-bore the pole at 11/16 in.
- Insert a 5/8 in through-bolt with a 4-in square washer on the back.
- Lift the V-brace into position, apex against the pole.
- Drive 1/2 in lag screws (or through-bolts) through the slots into the crossarm underside.
- Torque both ends to 80–100 ft-lb.
Buyer’s Guide: V-Type Angle Brace
1. When Do You Need a V-Type Angle Brace?
A V-type angle brace is a one-piece, inverted-V support fabricated from hot-rolled angle steel. Mechanically it replaces a pair of flat-steel braces in a single component, carrying 2–3 times the working load before deflection becomes a concern.
The decision between V-type and a flat-brace pair almost always comes down to load. A flat-brace pair handles routine tangent distribution comfortably; once you exit that envelope — transmission voltages, line-angle turns >30°, long spans >250 ft, or any 15+ kVA transformer on the crossarm — the flat brace starts to deflect under sustained pull and the crossarm begins to twist. The V-brace’s closed triangular geometry resists this twist because both diagonal members share the lateral load symmetrically. It also reduces installation labor: one brace instead of two, one bolt set instead of two. Equivalent to Hubbell 6941 and 6942 in catalog dimensions.
2. How to Choose the Right Size
Span and drop together set the load class.
- RAX-AB-48-14 — light-duty tangent, short crossarm
- RAX-AB-48-18 — standard distribution, the most-ordered size (Hubbell 6941 match)
- RAX-AB-60-18 — heavy distribution + light transmission (Hubbell 6942 match)
- RAX-AB-72-22 — transmission, dead-ends, heavy transformer
If your project drawing specifies a Hubbell catalog number, use the spec table cross-reference. If you’re sizing from scratch: pick the drop (vertical distance from crossarm to pole mount point) by available pole space — 14 in for compact construction, 18 in standard, 22 in for heavy-duty. Pick span (the brace’s full width) to match the crossarm’s working length. Custom span (36–96 in) and drop (12–30 in) available with 5–7 day tooling, 500-piece minimum.
