Key Features
Overview
The Klein Tools Flame-Resistant Beanie (FRBN11) is a knit winter hat made from flame-resistant fabric. This is an FR beanie designed for electrical and utility workers who need warm head coverage that is rated for arc flash and flash fire exposure.
A regular acrylic beanie can melt or ignite in an arc flash, which is why it has no place under an FR program. Klein knits this one from a blend of 47% modacrylic, 43% Tencel, 5% aramid and 5% spandex, giving head coverage rated for arc flash and flash fire hazards.
Warmth comes from the knit construction, which traps heat for extended outdoor work and long exposure on the jobsite. The fabric is soft and smooth to minimize irritation over a full day, and the spandex content gives it a stretch fit that suits most head sizes.
The orange color is high visibility, which helps in low light and in high-traffic work zones. The beanie weighs 3.8 oz (108 g), measures roughly 8-5/8" x 10-3/4" (21.9 x 27.3 cm) flat and is machine washable.
Who should buy it: linemen, utility crews, electricians and industrial workers who work outside in winter and need head coverage that matches the FR rating of the rest of their gear.
