Snow Guards For CR Systems

Snow guards for CR Systems standing seam panels help manage snow and ice near entrances, walkways, vehicles, equipment, and other areas below a roof. Product selection depends on the exact profile: CRS 25/CRS 38, CRB, or CRC.

Compatible CR Systems snow retention options include adhesive-mounted polycarbonate guards on all three panel groups. CRS 25/CRS 38 also accepts the compatible non-penetrating clamp-on products identified below, subject to a test fit and project-specific layout.
  • CRS 25 and CRS 38 have mechanically seamed profiles; both adhesive and clamp-on options are listed below.
  • CRB and CRC use batten covers, limiting them to the adhesive-mounted products listed.
  • Roof pitch, panel width, snow load, roof length, metal, surface condition, and complete system layout affect final selection.
Important: Do not select a snow guard by appearance alone. A clamp that fits CRS 25/CRS 38 may not secure to the CRB or CRC batten cover. Do not attach screw-down guards through concealed-fastener standing seam panels. Confirm panel identity and attachment method before specifying a system.

Use these profile-level pointers first, then confirm each product in the compatibility chart.

  • CRS 25 / CRS 38: Adhesive-mounted polycarbonate guards and compatible clamp-on rails or SnoCleat RC/RCT products. Test-fit clamps before ordering.
  • CRB: Adhesive-mounted polycarbonate guards only; the batten cover prevents the clamp-on products in this chart from gripping the panel correctly.
  • CRC: Adhesive-mounted polycarbonate guards only; the batten cover prevents the clamp-on products in this chart from gripping the panel correctly.
  • Standing seam warning: Do not use screw-down snow guards on these concealed-fastener profiles.

About CR Systems Roofing Systems

CR Systems, Inc. is a Texas roofing company founded in 1996 by Rayne Knight. Its standing seam profiles covered here are CRS 25/CRS 38, CRB, and CRC. Confirm the installed profile before choosing adhesive guards or a clamp-on system.

The compatibility chart distinguishes adhesive polycarbonate products from seam-mounted rails and individual clamps. Adhesive options are shown for all three profile groups; clamp-on systems appear only for CRS 25/CRS 38. Explore snow guards for metal roofs, then use the panel-by-panel results below. “YES” means the product is shown as compatible for that profile; “NO” means it is not shown as a fit.

Snow Guards for CR Systems Standing Seam Roof Panels

CRS 25 has a 1-inch seam and a 17-inch panel width; CRS 38 has a 1.5-inch seam and a 16-inch panel width. CRB has a 1.75-inch batten seam and a 17-inch panel width. CRC uses a batten cover, with 1-inch or 1.5-inch seam heights and a 15-inch panel width. Their different seam details determine which attachment methods work.

Standing seam warning: Do not install screw-down snow guards through concealed-fastener CR Systems panels. Use a compatible clamp-on assembly only where the seam allows it, or an adhesive-mounted guard where a suitable bonding surface exists.

The wide batten covers on CRB and CRC do not provide the secure seam grip required by the clamp-on products listed in this chart. Use compatible adhesive-mounted polycarbonate products on suitable panel surfaces.

Check that adhesive can bridge any panel striations without gaps. Test-fit seam clamps on CRS 25/CRS 38 before ordering a full rail system, and consider IceStopper components where ice could pass beneath a rail.

CR Systems Snow Guard Buying Checklist

  • Confirm the exact CR Systems profile and inspect its seam or batten cover.
  • Match the attachment method: adhesive for suitable panel pans; clamps only for compatible CRS 25/CRS 38 seams.
  • Check ground snow load and identify areas where sliding snow or ice could create hazards.
  • Request a complete roof layout based on slope, roof length, panel width, and expected load.
  • Order a test-fit unit before committing to clamp-on components for a project.
  • Plan adhesive cure time: SureBond SB-190 needs approximately 28 days at 50°F or warmer to fully cure.

Compatibility Guidance Note

SnoBlox-Snojax bases the compatibility information presented in this guide on product testing and field experience with CR Systems metal roof panel profiles. Panel manufacturers periodically update profile specifications, and project variables such as seam condition, coating type, and installation method can affect outcomes. Customers should confirm current panel specifications directly with CR Systems and contact SnoBlox-Snojax with project-specific questions before ordering.

Snow Guards for CR Systems Metal Roofing Panels – Compatibility & Installation FAQ

The answer depends on the panel profile. CRS 25 and CRS 38 can use compatible adhesive-mounted polycarbonate guards and selected clamp-on systems. CRB and CRC panels are limited to the compatible adhesive-mounted guards shown in the chart.
Yes, the chart lists compatible SnoCleat RC/RCT products and SnoBar and ColorBar rail systems for CRS 25 and CRS 38. Test-fit a clamp on the installed seam before ordering a full system.
The CRB panel has a separate batten cover that does not provide the secure panel grip required by the clamp-on products in this chart.
No. The CRC batten cover prevents the listed clamps from attaching securely to the main panel.

The chart lists IceJax I, IceJax II, Ecojax, SnoBlox Deuce, SnoBlox Ace, SnoJax II, and SnowBreaker for CRS 25/CRS 38, CRB, and CRC.

Do not fasten screw-down snow guards through the concealed-fastener standing seam panels covered in this guide. Choose a compatible adhesive-mounted product or, for CRS 25/CRS 38, a suitable clamp-on system.

Striations can leave gaps beneath a guard. Check that the panel provides a suitable bonding surface, follow the adhesive instructions, and confirm the guard can bond properly without gaps beneath it.

Allow about 28 days at 50°F or warmer for a full cure. Plan the installation window before snow is expected.
No. The chart identifies product fit by panel profile. The number and placement of guards or rails also depend on factors such as roof slope, run length, panel width, and snow load.
Compare your roof’s seam or batten shape and dimensions with the profile information in the CR Systems blog. If you are unsure, contact SnoBlox-Snojax with clear photos and measurements before ordering.
