The Kit comprises of most commonly used DRYWALL ANCHORS / RAWL PLUGS / GITTI. These expansion anchors are ideal for fixing handles, folding shutters, or down-pipes in concrete aerated concrete, solid gypsum panels, and in all other solid and hollow building materials. EASY TO INSTALL and DIY friendly. To install, a pilot hole is drilled in the wall, the anchor is fitted into the hole, and then a hammer is used to lightly tap the anchor head flush with the wall. A drywall anchor goes between the screw and the drywall, biting into the drywall much more effectively than a screw would. Then, you screw into the anchor, so everything stays in place. Drywall anchors offer you the most effective solution for hanging or installing almost any type of item to drywall especially when there is no convenient stud located behind the wall. The anchors are a great choice for LIGHT TO HEAVY DUTY wall-mounting projects so you can use the anchors for pictures, shelves, bathroom accessories, curtain rods, mirrors, water purifier and many more DIY home installations.
