SnoCleat SC2B Double Bar Snow Guard for PBR & R-Panel Metal Roofs

What the SnoCleat SC2B Is

The SnoCleat SC2B is a tall-profile aluminum snow guard for screw-down PBR and R-panel metal roofs. The unit pairs the MRM Mount and a 4-inch-wide aluminum face with six predrilled fastener holes and a die-cut foam gasket - with the SC2B Screw Down 2-Bar Bracket bolted on top. The result is an individual snow guard with significantly more height than the standalone SnoCleat PBR, providing greater snow-stopping surface against a sliding snow load.

Like the standalone SnoCleat PBR, the SC2B is installed in staggered rows across the roof rather than as a continuous bar. Each unit mounts on the panel flat between minor ribs, with #14 roofing screws driven through the panel into the structural purlin below. Staggered placement distributes retained snow load evenly across the roof plane and lets every panel carry its share of the load - no single fastener, purlin, or panel section is overloaded. The SC2B's added height makes it the right choice when standard SnoCleat PBR pads aren't tall enough for the snow load - heavy-snow regions, steep-pitched roofs, and projects where a taller individual guard is preferred over a continuous bar rail.

How the SC2B Stacks

Why the Added Height Matters

A guard buried by accumulated snow stops contributing - the snow pack rides over the top and the load transfers entirely to the guards downslope. The SC2B's bracket-on-base configuration raises the effective stopping height of every guard in the row, which is why it's specified for heavy-snow regions and steep-pitched roofs where standard SnoCleat PBR pads may be undersized.

Installed in Staggered Rows

The SnoCleat SC2B is never installed in a single row across the eave. Like the standalone SnoCleat PBR, it must be installed in staggered rows running the full length of the roof section being protected. Multiple rows up the slope distribute the retained snow load evenly across the roof, so no single guard, fastener, or panel section is overloaded. Row count and spacing depend on roof pitch, panel dimensions, ground snow load, and panel length - your free engineered layout returns the exact placement for your project.

Right Project, Right System

Panel Compatibility

The SnoCleat SC2B is purpose-built for exposed fastener metal roofs - PBR, R-panel, AG panel, U-panel, and similar ribbed through-fastened profiles. The base mounts on the panel flat between minor ribs with #14 roofing screws driven through the panel into the structural purlin. For confirmed compatibility with specific manufacturer panel profiles, reference the Snow Guard Compatibility by Roof Manufacturer guide.

What Ships in the Unit

Sold as a single SnoCleat SC2B unit. Each unit includes:

1. Confirm the staggered-row layout. Use the project-specific layout supplied with your order. Every guard must land on a structural purlin. Multiple staggered rows up the slope are required - never install in a single row at the eave.
2. Locate purlins, mark guard positions. Most through-fastened roofs have visible panel screws aligned with each purlin - use those as your guide. Mark each row with a chalk line and stagger the next row's guards between the previous row's positions per the engineered layout.
3. Apply foam gasket to base underside. The die-cut gasket eliminates the need for liquid sealant or adhesive. No glue, no caulk, no mess.
4. Set the SnoCleat PBR base on the panel flat. Center between minor ribs over the purlin. Drive a minimum of three #14 roofing screws through the predrilled holes into the purlin. Use all six fastener locations for steep pitches or heavy snow loads. Seat fasteners so the bonded washer just compresses - do not overdrive.
5. Bolt SC2B bracket to the top of the base. Tighten the top bolt with a 9/16″ hand wrench.
6. Continue across the row at the engineered spacing. Every guard must land on a purlin. Spacing varies by snow load, panel type, and purlin spacing.
7. Lay out additional staggered rows up the slope. Per the engineered layout, with each row's guards staggered between the previous row's positions. Always landing each guard on a purlin.

Design Requirements Before Installation

• Load path. All retained snow loads transfer through the SnoCleat PBR base, through the panel, into the structural purlins. Panel attachment and purlin capacity must be evaluated before installation.
• Minimum panel. 26-gauge steel over wood purlins or 24-gauge over steel purlins, with panel fasteners correctly installed at the panel manufacturer's recommended spacing. Do not install on panels with loose, pulled, or under-driven fasteners - correct panel attachment first.
• Fastener count. Minimum of three #14 roofing screws per base. Use all six predrilled locations for maximum holding strength on steep pitches, heavy snow loads, or where the project specifies enhanced anchorage.
• Staggered rows required. Never install in a single row. Multiple staggered rows up the slope are required to distribute the retained snow load evenly across the roof plane.
• Purlin landing. Every guard must land where it can be fastened through the panel into a structural purlin. Guards fastened only to the panel sheet will fail under load.
• Eave overhang. Where the eave overhangs unsupported framing, confirm the overhang can carry retained snow load - otherwise place the first row at the bearing wall or first purlin.
• No isolated areas. Never install only over doorways, vents, chimneys, or partial roof sections.
• Coverage limits. No snow retention system retains 100% of snow and ice. The SnoCleat SC2B is designed to mitigate the dangers of sliding snow and ice across the full roof plane.
