These Surebonder Upholstery Staples, 3/8" length, come 5000 per pack. These fine wire 22 gauge staples have a thin wire which allows them to penetrate all types of upholstery. They have a 3/8" crown (width), so they are wide enough to secure the wire and narrow enough to put in tight places. We recommend these with Surebonder's 9615A pneumatic upholstery stapler.
