The Prest-On Insta-Back drywall fastener is applied to the 4' edge, it can also be used for repair back-up. The Insta-back eliminates the need to cut wallboard back to the nearest stud, making for quick, easy repairs. The Insta-back lets you "back-block" wallboard four-foot edge to four-foot edge, to make finished butt joints that are "bump-free", with no ridges or crowns. Reduce the number of joints to be finished saving time and material. Drywall screws and Insta-backs create a joint between studs as strong as a solid sheet of board. The Insta-back features scored tabs that break away so that no metal is exposed. Insta-backs at the bottom edge assure a solid bond between upper an lower wallboard panels. Install ceilings faster, easier and safer, while eliminating sagging wallboard between trusses. The patented lance design provides a 1 to 2 degree taper for a perfect finished joint. Insta-backs eliminate time-consuming measuring and cutting, and reduce scrap.
