American Tech Supply, a registered CCR contracting supply company has teamed up with Alcoa, Highline Products, Carlon, Commscope, and several other leading osp fiber optic underground equipment manufacturers. Just click on any of the OSP fiber optic enclosures below.ATS carries several models of OSP enclosures from several manufacturers including the CMPH is a versatile OSP closure designed for both new provisioning installations as well as rehabilitation of existing access points housed in metallic enclosures. The CMPH’s superior structural strength, outstanding environmental protection.

Pull boxes can be used next to the Control Buildings.
for extra cable training room. Pull Boxes can stand alone and be used by themselves with conduit for pulling cables.These are just a few examples of Pull Boxes with different cut outs, hole sizes, and configurations.
Highline can manufacture custom Pull Box layouts with customers request. Are used in the underground distribution of power and signals. They provide access to the buried lines and allow an area for splicing and pulling of cable or housing of in-line equipment.
