Skylight Screen - Model STS

The supplied installation information estimates less than 10 minutes for two workers once materials are staged, although actual installation time can vary based on skylight size and configuration.

Use this measurement form, which can also be found under the product's resources tab. Provide your skylight curb’s length, width, and dome height when you contact Safety Rail Source to order custom-fitted screens ready for immediate installation.

Yes. The main difference lies in how they attach to your roof and the specific roofing material they are designed to protect.

• Curb-Mounted Screens: These screens mount directly to a raised wood or metal box structure (the "curb") built around the skylight. They secure tightly around the perimeter of the existing frame and are typically used on flat or low-slope membrane roofs.
• Standing Seam Screens: These specialized screens are designed specifically for standing seam metal roofs. Instead of attaching to a wood curb, they use non-penetrating clamps that grip the raised metal ribs of the roof panels. This allows the metal roof to expand and contract naturally without causing leaks or structural damage.

Choosing the right one: Always match your screen selection to your existing roof profile and skylight style to ensure proper OSHA fall-protection compliance. Contact our experts about your specific project.

No. The standard STS installation uses a non-penetrating compression system that clamps to the outside of the skylight curb rather than fastening through the skylight frame. Certain longer configurations, including units over 105", require additional attachment according to the installation instructions.

Yes, the Model STS is designed and tested to comply with OSHA requirements applicable to skylight fall protection. Documented testing performed on September 4, 2019 showed the tested screen supported a 622-lb applied load without failure.

OSHA requires employers to protect workers from falling through holes, including skylights, that are 4 feet or more above a lower level. The Model STS is designed and tested to comply with OSHA 29 CFR 1910.28(b)(3)(i) and the applicable cover requirements of 1910.29(e)(1).

The STS model was tested by Kee Safety on September 4, 2019, with a 622-lb load applied at the front end and center of a 5' x 10' skylight to simulate worst-case point loading. The screen supported the applied load without failure, with a maximum reported deflection of 4" at the front end and no visible damage to the fixings or skylight after the load was removed. This test result exceeds California's 400-lb minimum strength requirement for skylight screens.

Under California Title 8 §3212, skylight screens must support the greater of 400 lbs. or twice the maximum intended load imposed on the screen. Cal/OSHA applications may require configuration-specific engineering or installation considerations. Contact Safety Rail Source to confirm the appropriate STS configuration for your project.
