The Bostitch Industrial 20-Gauge 9/16" x 1/2" Medium Crown Pneumatic Autofire Long Magazine Fine Wire Stapler (21680B-ALM) drives 80 series fine wire staples from 1/4" to 1/2" in length. This Upholstery Stapler is extremely quiet and features a very lightweight yet rugged all metal design. You can use the same hand that activates the trigger to open the magazine, allowing for new staple insertion with your free hand. The Stanley Bostitch 21680B-ALM works well for securing fabric to wood frame, pre-upholstery spring-up operation attaches cardboard, webbing and Propex to frame, and boat seating with stainless steel staples.
