Tackform 11in DuraLock 20 Series Carbon Fiber Arm - Durable

In this review the Tackform 11in DuraLock 20 Series carbon fiber arm earns its place for users who need a rugged, repeatable mounting solution for phones, tablets, GPS units, and accessory gear. The biggest reason to buy is reliability: Tackform engineers an internal support system that ties the two dovetail/socket ends together so the sockets do not simply pull out over time, which is a common weak point on lesser tube arms. For anyone running a fleet, motorcycle, SXS, truck, or point-of-sale setup where failure is not an option, this arm delivers solid long-term performance.

Key Features

• Compatibility: Works with Bulletpoint, 67 Designs, iBOLT and other systems using a 20mm ball and socket, so it fits many existing mounts without adapters.
• Reinforced construction: An internal support system connects the dovetail/socket ends to prevent the common separation failure found on glued socket arms.
• Durability: Carbon fiber construction with engineered load capacities offers a safety factor beyond typical aftermarket arms for repeated daily use.
• Optional anti-theft: Convertible couplers allow the socket to be loosened for repositioning while preventing the ball from coming free, useful for unattended vehicles and point-of-sale displays.
• Length and reach: Overall length is 11in with a 10.16in center-to-center measurement, making positioning predictable for dash, cockpit, or console installs.
• Custom accents available: Optional CNC machined accent kits and knobs let users match vehicle color schemes or add subtle styling.

Who It's For

This arm is ideal for installers, fleet operators, and riders who need a dependable mounting arm that will not fail under repeated vibration and use; the internal reinforcement and tested load capacities make it suited to heavier device setups like tablet mounts and larger GPS units. It also suits anyone who already owns 20mm ball accessories from the listed manufacturers and wants an upgrade that reduces the risk of sudden failure.

Users who should look elsewhere include those on a very tight budget who need a basic temporary mount or buyers who require an integrated mounting head (this product is the arm only). Also consider alternate lengths if a shorter or longer center-to-center reach is required for a specific installation.

Pros & Cons

Pros

• Exceptional build quality with an internal support system that prevents socket separation.
• Broad compatibility with 20mm ball systems from popular manufacturers for easy swapping.
• Optional anti-theft and accent kits add practical security and style without changing function.

Cons

• Sold as the arm only, so users must already have or buy compatible ball heads and bases separately.
• Only a single length option here, so installers needing a different reach must choose another model.
