The Vevor pneumatic staple gun is a lightweight 20-gauge upholstery stapler designed for woodworking, fabric work, furniture assembly, and DIY projects. It works with T50 staples in 7/16" crown sizes and staple lengths from 5/32" to 5/8". A large-capacity magazine holds up to 100 staples to reduce reload interruptions. The tool features sequential firing, a rotatable exhaust, and a non-slip rubber grip for safer and more comfortable operation. It requires an air compressor and operates from 70 to 110 PSI.
