This patented product has stood the test of time as an aesthetically appealing, low-cost solution to the problem of sliding snow and ice on metal roofing.

The SnoBlox Difference

SnoBlox Deuce Black Snow Guards are Strong

The SnoBlox Deuce revolutionized the patented polycarbonate snow guard industry with its low profile forward-mounted 2.5" high face and its sleek 1.5" wide waffled tapered back. The flat, forward face holds snow and ice in place without harming the integrity of your roof. The waffle base provides nearly triple the strength of smooth bottom guards of the same size.

Professional third-party Intertek/ATI tests demonstrate the SnoBlox Deuce holds 3456 pounds when attached with #14 screws and 1379 pounds when attached with the SB-190 adhesive.

SnoBlox Deuce Black Snow Guards Are Versatile

The versatility of this product makes it perfect for professional roofers and DIY homeowners alike. The mounting versatility of this product allows it to be mechanically attached to screw-down roofs with a 1.5" flat area or adhesive mounted on floating standing seam roof systems. They will fit most popular 36" R-panels with 12" rib spacing or 9" rib spacing without rib straddling.

SnoBlox Deuce Black Snow Guards Frequently Asked Questions (FAQs)

Our polycarbonate snow guards, crafted from virgin, UV-stabilized polycarbonate made in the USA, are a testament to our commitment to quality. While they may lose some shine over time, their UV stabilization ensures they won't fade, maintaining their durability and longevity.

We never advise mixing various system types. It doesn't matter if you combine different guards from the same company, comparable guards from other companies, or whole distinct systems; this is never a good idea. Usually, specific load ratings and purposes come into play while designing snow guards and rail systems. These different specs make developing an effective snow retention system from various types that work effectively nearly impossible. Competitors rarely share information or agree on spacing methodology, especially when combining products from other companies.

For our DIY-savvy homeowners, installing polycarbonate snow guards can be a breeze. We provide detailed installation instructions with your order and on our website. However, safety is paramount. Working on a metal roof with a sloped surface can be risky, so we strongly recommend using appropriate fall protection, such as the RidgePro, before installing and climbing onto your roof.

Snow guards made of polycarbonate should last as long as the roof, if not longer. Proper layout and installation ensure our products' performance and lifespan. For layout suggestions for your project, visit our spacing guidelines page. Clear and straightforward descriptions and diagrams take the guesswork out of this process.

Our clear snow guards are not just any plastic. We use 100% virgin polycarbonate, produced in the USA, to make these products, demonstrating our commitment to quality. Unlike some of our competitors, who source inexpensive plastics overseas, we ensure the highest standards. Thirty times stronger than acrylic, polycarbonate plastic is tough and durable. Our polycarbonate's UV stabilization further ensures the guards won't become brittle over time, giving you peace of mind about your investment.

About SnoBlox-Snojax

In the late 1970s, we embarked on a quest for an improved snow guard solution that would be non-corrosive and nearly invisible to preserve the building's aesthetic appeal. After extensive testing, we obtained a patent for Snojax®, the world's first screw-down, clear, non-corrosive, polycarbonate snow guard. In 1985, we innovated further with the release of Snojax II, the world's first glue-down polycarbonate snow guard. By 2000, we introduced two patented SnoBlox® models, "Ace" and "Deuce," offering an economical alternative and resolving the challenge of straddling minor ribs. These models boasted the industry's first patented waffled base design, enhancing adhesive bonding. In 2005, we expanded our offerings with Icejax I and Icejax II, which were validated through rigorous testing by the renowned ATI professional testing laboratory. Our Snojax®, SnoBlox®, Icejax™, and SnowCatcher™ brands are the epitome of robust snow guards in the industry, validated by comprehensive testing.
