2 Inch Master Gripper Wood Purlin Snow Guard Screw

Our polycarbonate snow guards, that screw down, each require two screws. Near each guard's face, there are molded starter points or pre-drilled holes. Our SnowCatchers have three holes, two of which are necessary for attachment and are also located close to the face. If you decide to paint them or powder coat them, the third hole on the base's opposite side is primarily used as a hanging point. Additionally, this hole may serve as a supplemental attachment point. The SnoCleat PBR, SnoCleat 2.67, SnoBar/ColorBar PBR, and SnoBar/ColorBar 2.67 screw-down snow guard and snow rail systems require at least three screws per guard or bracket, though they can each utilize as many as six.

The majority of our polycarbonate pad-style snow guards include molded starter points. Our self-tapping 2" Master Gripper screws can easily drill through this material. As such, pre-drilling the guards is optional. Pre-drilled holes come standard with the Snojax 1, stainless steel SnowCatchers, and the aluminum SnoCleat PBR and SnoCleat 2.67 snow guards. All of these models are compatible with the Master Grippers.

Roof leaks shouldn't occur if a snow guard system has been installed correctly. Make sure to use screws with neoprene washers and pair them with either foam gaskets for metal snow guards or liquid silicone for polycarbonate snow guards. Many customers decide against adding new roof penetrations for snow guards. They will choose, instead, to install a glue-down snow retention system using the Surebond SB-190 adhesive.

Due to most of our snow guards either coming in a clear finish for our polycarbonate styles or bare metal finish for our mill SnowCatchers and SnoCleats, we currently offer our screws in only a standard silver finish. There are thousands of roofing colors currently available from hundreds of roofing manufacturers. Because of this, maintaining stock of all possible color matches would be cost prohibitive and nearly impossible. Customers can choose to provide their own screws when a color matched screw is desired. We recommend that the screws used in these situations are comparable to those that we offer in both sizing and material.

The majority of our screw-down snow guards can be installed using one of the two screws that we offer. For wood purlins and substrate, use the Master Gripper which is a 2" long #14 self-tapping screw, whereas the Master Driller is a 1.5" long #14 self-tapping screw designed for use with metal purlins. Both of these fasteners have neoprene washers, are silver in color, and are made of case-hardened carbon steel. The SnoCleat 2.67 and 2.67 rail systems utilize a 3" screw because they straddle a wavy corrugated panel's high ribs. Longer screws can be required, depending on whether or not there is insulation under the panels.
