These metal tack strips are used by both large furniture manufacturers and custom upholstery shops. Tack strips are commonly used on the front of arms and the outside backs of furniture. Can be used anywhere that tacking is needed to finish the edges. Regardless of whether you are building a new couch or doing some re-upholstery work on an old chair, these are the best. Be certain that the fabric is going to stay securely in place for years to come. The tack strip measures 0.5 wide by 24 long and can be cut to length with tin snips if needed. The spikes measure 5/8 long(SIZE 8) allowing for fabric to be held securely to most any wood or plywood. Still MADE IN THE USA right here in the Furniture Capital of the World-High Point, NC
