Introducing the 4 Piece Furniture Leg Leveler Set by POWERTEC.These heavy duty leg levelers are designed to provide stability, lifting and balancing support for a wide assortment of home furniture and workshop equipment. They were engineered with a premium and sturdy build so that they could help prevent your applications from wobbling, tipping, vibrating and distributing disproportional weight to your components. Their design also allows them to serve effectively as furniture feet, woodworking table legs or non-marring base supports – and they make it easy to move and push applications that are too heavy to lift.For Quick and Easy SetupSimply pre-drill installation holes into the furniture at preferred site of attachment. Due to the wide variety of density and grain in wood, we recommend you test your insert in the same species of wood you are using for your project. To avoid damaging your threaded inserts, which are installed using a 10 mm hex wrench, you should start with a large hole (between ½” to 9/16”) and work your way down to the best fit. Once attached, adjust to the desired height with a 13mm hex wrench (not included).SupportPer Unit: 550lbs | 2200lbs total capacity for all four levelersDimensionsCarbon Steel Bolt body: 3/8”-16 by 2; Chrome Polished Pad Base Dia 1-3/8” with White PA Nylon Pads; Zinc Tapered Threaded Insert is a nominal 1” high; (Please check for corresponding internal measurements)Commonly Used Furniture ApplicationsDesk, Chairs and Table Leg LevelersCabinet Shelf InstallationsFoot Rest Leg LevelerArt Easel, Plant and Display Stand LegsPOWERTEC is a leading manufacturer of high quality woodworking tools and accessories, machines, and an assortment of OEM replacement parts.
