KEENTECH Pneumatic 21 Gauge Staple Gun with 3000 Staples – Upholstery & Trim

Overview

The KEENTECH Pneumatic Staple Gun is a lightweight, reliable tool designed to streamline upholstery, trim work, and light wood projects. Weighing about 1.82 pounds, it balances in your hand with a comfortable rubber grip, helping you work longer without fatigue. Its compact profile makes it a versatile companion for tight corners and delicate fabrics alike.

This kit is built to be a ready-to-use solution right out of the box. It accepts standard 21-gauge crown staples ranging from 1/4" to 5/8" in length, and it operates at a practical 60–120 PSI. The tool ships with 3,000 staples in total, distributed as three bundles (8006/8010/8016, 1,000 pieces each) plus oil for maintenance, so you can get started on your next project without immediate shopping trips for supplies. The 1/4" NPT air inlet is compatible with common compressors, though an air compressor is required for operation and is not included with the kit.
