The Schlage Vehicle Hasp has a solid hardened steel body, which resists attacks by cutting, sawing or hammering. The sides create a shrouded environment for the padlock for maximum security against prying attacks. The Schalge Vehicle Hasp is secured with a Hockey Puc Shackle-Less Padlock (sold separately). Great for use on commercial vans, trucks and trailers. Fix to vehicle using coach bolts (not supplied).
