Installation Instructions

Drift Corrugated Series Bolt-Down Fence-Style Snow Guard Installation

Installation of bolt-down 1-pipe fence-style snow guards on corrugated metal roof panels.

Obtain the appropriate fasteners for your particular installation. Contact Rocky Mountain Snow Guards or a structural engineer for recommendations.

Instruction Steps:

1)

Locate and mark installation locations for Brackets in accordance with the layout pattern provided by Rocky Mountain Snow Guards. Generally, Drift snow fences are installed 12” above the eave edge. Additional rows of snow fences may be required above the eave row depending on specific job conditions. Drift Corrugated Brackets are to be fastened into solid wood blocking or into the roof support structure.

2)

Using a Drift I Corrugated bracket, mark locations for each of the 4 fasteners at each bracket location.

3)

Drill 3/8” holes through the corrugated panel where marked in step #2. Drill pilot holes into the decking and blocking for 3/8” lag bolts.

4)

Apply sealant on top of the corrugated panel around the holes drilled for lag bolts.

5)

Place brackets with bracket holes and corrugated panel holes aligned.

6)

Place and tighten 3/8” x 3.5” lag bolts into each bracket. Use ALL THREE(3) lag bolts per bracket for optimal strength.

7)

Complete fence-style snow guard system component assembly.

Tools Needed

  • Drill with 3/8" drill bit
  • Appropriate sealant
  • 3/8" x 3.5" lag bolts (3 or 4 bolts, depending on snow guard model)
