Half Clamp 1.25in

The Half Clamp 1.25in from ALLSTAR PERFORMANCE is a precision roll bar accessory clamp engineered for builders and fabricators who demand reliable tube attachment without welding. Designed for 1-1/4 inch outer diameter (OD) tubing, this clamp-on solution addresses a critical need in custom chassis work, roll cage assembly, and suspension modifications where non-destructive mounting is essential. Whether you're reinforcing a frame, mounting supplementary bracing, or securing auxiliary components, this single-hole fastening system provides repeatable, adjustable clamping force that preserves tube integrity.

Machined from aluminum and finished in black anodize, the Half Clamp 1.25in features a single 3/8 inch hole for bolt-through mounting and incorporates a half-round profile that distributes load evenly across the tube's outer surface. The anodized finish resists corrosion in harsh under-car environments while maintaining a clean aesthetic on show builds. Its compact footprint—measuring 4 x 0.5 x 6.95 inches and weighing just 0.11 lbs—makes it ideal for tight spaces where full-wrap clamps would interfere with other components. The aluminum construction keeps overall system weight minimal, a critical consideration in performance applications where unsprung mass directly impacts handling and braking.

This clamp serves fabricators, hot rod builders, and suspension specialists who routinely work with mild steel or chromoly tubing in the 1-1/4 inch range. Installation requires only a 3/8 inch bolt and matching fasteners—no welding, grinding, or heat required—making it ideal for temporary test fits, quick-change setups, or permanent installations where heat stress must be avoided. Pair multiple clamps for added stability on longer runs, or use singly for light-duty mounting of shock absorbers, brake lines, fuel cell brackets, or auxiliary cooling lines. Each clamp is sold individually, allowing you to purchase exactly the quantity your build demands.
