Anthes, a division of Gleason Corporation, manufactures high-quality Weathercaps designed to protect trucks, off-road vehicles and equipment with vertical exhaust stack systems from dirt, dust, debris, snow and rain. These Weathercaps feature a counter-balanced structure with a hinge point to enable instant and tight cap closing, even in abnormal parking angles, and a full-vertical position opening with the slightest stack pressure for allowing the engines to breathe freely. Anthes Weathercaps can be installed easily using a single bolt, without drilling holes or clamps. Selected models also come equipped with a Lock-Bar security option. These Anthes Weathercaps are available in different outer diameters and colours on Raptor Supplies.
