Description
Equip your truck with the Kleinn 412 direct-fit single chrome-plated roof-mount air horn system, featuring a single premium 25-inch chrome-plated stainless steel trumpet equipped with a unique rectangular opening and protective horn cover to keep road debris out of your system. Engineered for universal semi-truck and commercial vehicle applications, this heavy-duty roof-mounted configuration allows you to command the road with a deep, authentic, and loud over-the-road big-rig blast. Designed for clean external mounting on custom or commercial rigs, this high-performance horn kit features a 1/4-inch airline input that requires an onboard pressurized air system and can be operated using a manual hand-pull air valve or an electronic solenoid valve. For a proper, leak-free setup right out of the box, the installation requires a Model 330 Roof Mount Air Horn Fittings Kit, providing the ultimate balance of glistening chrome style and serious acoustic presence that heavy-duty custom truck builds count on.
25" Single chrome plated zinc alloy roof mount truck horn, square trumpet end with horn cover (no air valve or solenoid included 330 pack needed).

My ARE truck bed cover was off line & not closing properly. The repair was not an easy fix but they took their time & made sure the bed cover closed perfectly & I can now lock my bed securely again with my key fob! The price I was charged was very fair even though the job was time consuming! I am a fan & will definitely be back! Excellent customer service. & very friendly!

I’ve bought 3 camper shells, 3 lift kits, a aftermarket bumper install, and a leveling kit from H&H. They’re a little pricier, but they do good work. No issues with any of the trucks I’ve sent to them.w

I recently had a tonneau cover installed on my truck and was very pleased with the customer service that I received. The associates were very helpful, were great to work with and did an exceptionally well job with the installation. I highly recommend H & H to anyone who is considering doing any truck upgrades. Also, an extra thanks to Cary for all the assistance he provided.

Trevor and his team did an outstanding job delivering my new 10' by 16' aluminum shed to a very tight delivery location. The shed is outstanding and I was glad I went with Thrifty Portable Building. I highly recommend them if you are looking for a portable building.
