FirstSpear Tubes™ Quick-Release Technology

FirstSpear Tubes™ fasteners provide a practical alternative to traditional hook-and-loop closures and conventional buckles.

The system uses a controlled two-motion release mechanism that can be operated with one hand. Once engaged with a compatible male Tubes™ component, it provides a secure connection that can be released quickly when required.

The design also helps reduce unnecessary material overlap and maintains consistent equipment adjustment between uses.

Split-Bar Attachment

The female split-bar configuration is designed for integration with compatible sewn webbing loops, making it useful for equipment upgrades, repairs, and custom tactical gear configurations.

Its 4-inch format is suited to compatible plate carrier and cummerbund attachment systems.
