Overview

Meet the Tackform DuraLock 20 Series 2" long metal ball-and-socket arm. With dual 20mm sockets, this arm provides stable support for devices and accessories, while offering flexibility for quick re‑positioning. It is designed to integrate with popular 20mm systems from brands like Bulletpoint, 67 Designs, and iBOLT, delivering a reliable mounting solution that emphasizes continuity under road vibrations, trail chatter, or transit bumps. The black finish delivers a sleek, low-profile look that blends with most rigs.

Durability, engineering, and a security option

Engineered for longevity, the DuraLock 20 Series emphasizes a rugged build and tested load capacity that stands up to daily use. While many 20mm components exist, this line highlights a built‑in safety margin and consistent performance across installations. An optional anti-theft knob (Patent Pending) adds a layer of restraint for environments where extra security is appreciated, helping keep angles fixed when parked or in crowded spaces.

• Compatibility: works with many 20mm ball-and-socket systems, simplifying cross-brand setups.
• Durability: designed to maintain position even through vibration and movement.
• Anti-Theft Option: optional knob provides added security in active environments.

Precision in a compact form

One of Tackform’s shortest double-socket arms, this model prioritizes quick repositioning with a single locking knob and a firm, slip-resistant hold. The design centers on the ball-to-ball spacing of 1.3 inches, enabling refined adjustments in tight spaces without sacrificing stability.

• Ultra-short reach: compact footprint suited for crowded dashboards or narrow mounts.
• Single-knob operation: fast repositioning with a confident lock to prevent accidental movement.
• 20 Series focus: optimized for the Tackform 20mm platform to ensure cohesive performance.

Real‑world use and fit tips

Ideal for riders, enthusiasts, and portable setups that require a dependable mounting point for gauges, modules, or compact devices. Use cases include motorcycle configurations, side-by-sides, or other compact rigs where a secure, adjustable arm matters. Important note: this arm is not designed for 25.4mm / 1" / B‑sized balls.
