The TTA94311 is a professional nailer for precision fastening, designated as 21GA TA116A/21-13, indicating compatibility with 21-gauge brad nails ranging from 13 mm to 21 mm in length. This device operates with a pneumatic system that requires compressed air supply, providing consistent driving power for reliable performance in woodworking, trim installation, and furniture construction. Made from durable materials such as a hardened steel magazine and an ergonomic rubberized grip, it measures approximately 28 cm in length, 18 cm in height, and 8 cm in width, weighing 1.2 kg for balanced handling during extended use. The angled magazine design allows access to tight spaces, while the depth adjustment wheel offers control over nail penetration from flush to countersunk. It features a quick-release mechanism for jams and requires an air compressor with a working pressure of 5-7 bar and a 6 mm air hose connection. This successor model of previous Max nailers maintains the brand's focus on reliability, with reduced recoil vibration and oil-free operation that minimizes maintenance. Suitable for professional craftsmen and demanding DIYers, it drives 21-gauge brad nails with a diameter of 1.25 mm, with a magazine capacity of 100 nails and exhaust diversion to direct air away from the user. The tool includes safety features such as a sequential trigger and a dry fire lockout to prevent accidental firing when the magazine is empty.
