2 inch 21 gauge pneumatic pinner from Senco Products, Inc. uses an oil-free NEVERLUBE design that eliminates the risk of oil spillover onto the work surface, helping keep finished pieces clean when you are pinning delicate moldings or trim. The ergonomic angled pistol-grip handle improves control of the tool for comfortable all-day operation, which supports steady handling on repetitive fastening tasks. A rear exhaust with embedded muffler directs air away from the work and reduces exhaust noise, which helps maintain a clearer line of sight and a quieter working environment around the piece. The reversible belt hook mounts to either side of the tool, so you can keep the pinner at hand whether you work left- or right-handed on ladders, benches, or assembly lines.
The TN21L1 21 gauge pinner uses a 1/4 inch swivel air plug at the rear exhaust, which allows the air hose to rotate as you reposition the tool, reducing hose drag when working along long runs of casing or panel trim. The NEVERLUBE oil-free design means the internal system is built to run without external oiling, so there is no added oil at the air connection that could migrate toward the work surface during operation. The ergonomic angled pistol-grip handle sets the hand in a natural line behind the ultra-narrow nosepiece, which helps align the nose with the fastening point when you are working close to edges or in confined cabinet interiors.
The 21 gauge pinner, part number TN21L1, is part of the Nailers and Accessories class within Woodworking Tools and Equipment, aligning it with applications that rely on fine fastening in wood-based materials. With a magazine that automatically conforms to fit different pin lengths between 5/8 inch and 2 inch, the pinner supports a range of light fastening tasks, from shorter pins on small profiles to longer pins on deeper trim sections. The ultra-narrow nosepiece reaches tight corners and other hard to reach areas, which is useful on detailed assemblies such as cabinet interiors, trim intersections, and intricate molding joints. The rear exhaust with embedded muffler and swivel air plug keeps the hose and exhaust directed away from the work zone, helping maintain control as you move the tool around assembled casework or along long moldings. A reversible belt hook that mounts to either side of the tool allows the pinner to stay close at hand between shots, which is helpful when you alternate between fitting parts and fastening them.
The NEVERLUBE oil-free design eliminates the risk of oil spillover onto the work surface, so finishes and raw stock stay cleaner when you pin parts in place prior to final sanding or coating. Last nail lockout prevents dry firing when the magazine empties, which reduces impact marks on the work surface at the end of a run. The dual trigger serves as an added safety precaution to prevent accidental fires, giving more deliberate control over each fastening, which matters when you work near exposed edges or visible faces. The low load indicator alerts you before the fasteners are exhausted, helping you plan reloads away from critical joints so pinning patterns stay consistent. The ergonomic angled pistol-grip handle improves control of the tool for comfortable all day operation, which supports accurate nose placement over many cycles. Combined with the ultra-narrow nosepiece, this handle geometry helps you position pins precisely into corners, reveals, or slender moldings while maintaining a steady, repeatable feel. The 5 year warranty backs these design elements for long-term use in professional woodworking settings.
The TN21L1 21 gauge pinner has a magazine that automatically conforms to fit different pin lengths from 5/8 inch to 2 inch, so it covers a broad span of light fastening tasks.

The ultra-narrow nosepiece allows easy access to tight corners and other hard to reach areas, which supports precise pin placement in inside corners and detailed profiles.
The low load indicator signals when fasteners are nearly depleted, so you can reload the 21 gauge pinner at a convenient point instead of encountering unexpected empty shots.
The TN21L1 21 gauge pinner uses a dual trigger as an added safety precaution to prevent accidental fires, and last nail lockout reduces dry firing at the end of a load.
The rear exhaust with embedded muffler includes a 1/4 inch swivel air plug, allowing the hose to rotate as you move, which reduces hose drag when positioning the pinner.
