Safety inspection cages and personal protection tunnels are designed for heightened worker safety. Cages and tunnels provide workers a sheltered area to repair and inspect a kiln, keeping them safe from the debris that commonly falls as coatings shrink and expand. Made of T6-6061 aircraft aluminum, the cages are lightweight (140 pounds) – as much as 50% lighter than the steel alternative. Personal protection tunnels provide masons safe passage in and out of the kiln. Made with aluminum sides and a steel mesh cover, tunnels are designed to withstand impacts of up to 250 pounds and can handle drops from up to 18 inches.
