ASG4025 Snow Guard Installation Instructions

Typical Roof Type:

• New/existing double lock metal standing seam

• New/existing snap lock metal standing seam

NOTE:

- ASG4025-AL clamps are designed to engage seams up to 3/8” thick. Some horizontal

seams may require additional hand crimping at the clamp location.

- On snap lock seams, the set screws should be opposite the open/overlap side of

the seam.

- Three set screws (included) are used in any given ASG4025-AL installation.- All set screws must be installed in the same side of the clamp.

Installation: 1. Position the clamps appropriately on the panel seam. Using a 3/16" Allen wrench

attachment tip for a 1/4" drive screw gun, tighten and re-tighten set screws as theseam material compresses. Most industrial grade screw guns are rated at 115inch-pounds tightening torque and will deliver between 115 and 150 lbs (13-17Nm) at the highest torque setting.

2. Install Pipes, Couplings, End Caps and End Collars (refer to Pipe Style Installation

Instructions). Ice Flags are optional.

Snow guard layout for pipe-style bracket • Contact the manufacturer for detailed layout.• Do not install runs of snow retention more than 100 feet long without a break to allow

for thermal expansion.• First row of snow guards is installed above outer most wall or support of the building.• Do not use as Fall Arrest Anchors.• Be sure that panels are securely fastened to the roof to absorb the loads being

transferred by the snow retention system.

General Installation Instructions for

1” Pipe-Style Snow Guard Accessories

All of our 1” pipe-style snow guard accessories fit all of our 1” pipe snow guards for through-fastened or clamp-to-seam applications. Ice Flags and Ice Screen must be installed on a system with at least two pipes. Accessories are available in aluminum, brass and stainless steel. Aluminum and stainless steel accessories can be powder coated. Internal couplings are not powder coated. Ice Screen is available in stainless steel and brass.

End Collars (PP65) The purpose of End Collars is to keep the pipes from sliding though the snow guard brackets. Pipe cannot extend past last bracket more than 6”-8”. An End Collar is required for each end of each pipe on each run of snow guards. A run should not exceed 100’ to allow for thermal expansion. See installation details below for required End Collar placement.

1. If using on a system with External Couplings (PP84): End Collars should beplaced over the end of each run of pipe, on the inside of the outermost brackets(Fig. 1). As the last pipe in the run is installed, the End Collar should be installed.The End Collars should be installed 1/2” from the brackets.

F ig .1

Note: on some three-pipe or hi-hole systems using the External Coupling, it may be necessary to place one End Collar further inside than the other End Collars (Fig. 2).

Fig. 2



2. I f using on a system with Internal Coupling (PP86) : End Collarsshould be placed over each end of each run of pipe (Fig. 3). Place the End Collarover the pipe and tighten the set screw until it no longer slides. The End Collarshould be within 1” of the snow guard bracket, spacing is 1/8” for every 10’ of pipe.For example, if the run of snow guards is 80’ then the End Collar should be 1”outside the bracket.

Fig. 3

Note: on some three-pipe or hi-hole systems using the Internal Coupling, it may be necessary to place one End Collar inside the bracket and the others outside (Fig. 4)

Fig. 4

End Caps (PP56)

End Caps keep moisture and insects from getting inside of the pipes.

1. Install the End Cap by pressing it into the end of the pipe (Fig. 5).

Fig. 5



External Coupling (PP84) The External Couplings are used to join pipes together.

1. Install pipe and slide external coupling over the enduntil the pipe end contacts the dimple.

2. Install the next pipe, sliding it in until it contacts thedimple (Fig. 6).

Internal Coupling (PP86)

The Internal Couplings are used to join pipes together.

1. Insert assembled coupling into the end of one pipe so that half of the solidaluminum shaft is inserted (Fig. 7).

2. Begin twisting the exposed half of the coupling in a clockwise motion until therubber gasket engages the pipe. Continue to tighten until the coupling cannot beeasily pulled out of the pipe (Fig. 8).

3. Slide the next section of pipe over the exposed half of the coupling. Twist the tubein a clockwise motion until the rubber gasket engages the pipe. Continuetightening until the tubing cannot be easily pulled apart (Fig. 9).

4. If the system needs to be unassembled, simply turn the pipe counter-clockwise untilthe pipes can be pulled apart.

Internal Couplings come assembled and ready for installation. If they come apart or loosened during shipment assemble per Fig. 10, above. Do Not Over-Tighten prior to inserting the coupling into the pipe. Over tightening the bolt will cause the gasket to expand and make installation of the coupling difficult.

Fig. 10

Fig. 9

Fig. 7



Ice Flags (PP95)

Ice Flags hang from the pipe between the brackets to help keep ice and snow from sliding underneath. Note: Ice Flags should not touch the roof surface.

1. The Ice Flags should be placed over the top or middle pipe on two-pipe or three-pipe systems.

For fixed three-pipe brackets (PP115, PP117, PP145, PP314, PP315, PP325) the Ice Flag should be installed on the top pipe. For adjustable three-pipe brackets (PP215, PP225, PP235, PP503), the Ice Flag should be installed on the middle pipe. For all two-pipe snow guards the Ice Flag is installed on the top pipe. The long leg rests against the uphill side of the pipes.

Use the bolt and nut to hold the flag in position. Silicone or adhesive (Fig. 11) should be applied between the ice flags and the pipes to keep the flag fromsliding. See Fig. 13 on the following page for placement.

a. The Ice Flag for the model ASG3000 sits between the pipes (Fig. 12).

Fig. 11: Silicone or Adhesive Fig. 12: ASG3000



Ice Screen (PP98)

Ice Screen comes in 4’ lengths, 5” high; for most installations it will need to be cut to size to fit between the snow guard brackets.

1. Place the Ice Screen behind (upslope) the installed pipes.

2. Place a U-bolt on the pipe and fit it through theopenings in the Ice Screen.

3. Place the backing plate behind the Ice Screen andinsert the ends of the U-bolt through the openings.

4. Tighten the supplied locking nuts.

Each length of Ice Screen includes 4 U-bolts, 4 backing plates and 8 locking nuts. Ice screen should be attached behind the bottom two pipes in a three-pipe installation (as shown below) or on both pipes of a two-pipe installation. Note: 2 U-bolts are to be used for sections 24” or less. 3 U-bolts are to be used for sections greater than 24”.

Typical Installation The illustration below shows the PP225 with End Caps, End Collars, Internal Couplings & Ice Flags installed. For fixed three-pipe brackets (PP115, PP117, PP145, PP314, PP315, PP325) the Ice Flag should be installed on the top pipe. For adjustable three-pipe brackets (PP215, PP225, PP235, PP503), the Ice Flag should be installed on the middle pipe. For all two-pipe snow guards the Ice Flag is installed on the top pipe.

Snow Guard Maintenance

All snow guards should be checked as part of a yearly roof inspection by an experienced roofing and snow guard inspector. Any defects in materials and workmanship should be reported to the manufacturer immediately.

Refer to the categories below for additional inspection information. Alpine SnowGuards will not be responsible for any snow guard system that has not been properly maintained.

Pad Style SnowGuards – fastened using mechanical fasteners

• Inspect each unit to ensure snow guard assembly is intact.

• Inspect fasteners into the roof deck wherever possible.

Pad Style SnowGuards – adhesive mounted


• Inspect sealant around the perimeter. Remove and reapply any areas that are no longer watertight.

• Inspect units for slippage or peeling of the tape.

• Remove and reinstall these units.

Pipe Style – fastened to roof deck


• Inspect all fasteners in to the roof deck wherever possible. Inspect any snow guard relatedwaterproofing and replace or repair where necessary to ensure roof integrity.

• If any tubing has bent or shows any other evidence of failure or damage, contact the manufacturerimmediately.

Pipe Style – clamped to standing seam


• Inspect and check each set screw with a torque wrench to ensure proper fastening has been maintained.

• If any tubing has bent or shows any other evidence of failure or damage, contact the manufacturerimmediately.
