The STS Screens by Tie Down Safety provide skylight fall protection by protecting people from falling through skylights. The STS is a non-penetrating skylight screen that does not alter the structural integrity of the skylight itself. The STS Screen mounting frame consists of 2 aluminum extruded rails that rest on the outside frame of the skylight. The STS frames connect with 2 5/16” zinc plated threaded rods installed on the short sides of the skylight. The STS Screens lock into place with 1” aluminum clips and a d ½” hex head screws. The STS Screens vary from 12” – 70” wide and 12”- 128” long. Tie Down Safety also offers the STS Screen as CAL-OSHA compliant skylight fall protection. Tie Down Safety maintains high standards and quality controls using quality raw materials and component parts made in the USA.
