The Grabber's GW5 model has extradeep groove tabs for use on wet softwood decking and wet pressure-treated decking
Grabber has three metal clip models, all made of steel covered with a proprietary coating that is suitable for all locations except coastal areas. The G5 is the flagship model and fits a variety of grooved deck boards, spacing them 13/64 in. apart. The GTT5 is sized specifically for TimberTech. A third model, the GW5, is unique. It has extradeep groove tabs for use on wet softwood decking and wet pressure-treated decking that is expected to shrink after installation. Deck boards installed with the GW5 need to be slotted with the PowerBlade, a special router bit that cuts the extradeep recess and undercuts the decking edge beneath the slot. This permits the deck boards to be installed tightly together in anticipation of shrinkage, and the long tabs hold in the groove even after shrinkage.
The Grabber fasteners can be installed by hand or by using Grabber’s PowerDriver installation nailer and pneumatically driven screws.
