(931 companies)
Access control systems are used to identify people before granting access to secure facilities.
Overhead Doors
(179 companies)
Garage doors are designed to enclose and protect the entrances to garages and other large structures.
Access Points
(219 companies)
Access points are transmitter / receivers (transceivers) that connect to a network through an interface such as a bus or connector. They receive, store, and transmit data between the wireless LAN and the wired structure.
Door Viewers
(21 companies)

Exterior doors are designed and constructed for outdoor use. They allow personnel and equipment to enter and exit from buildings.
Preload Springs, Spacers, and Washers
(92 companies)
Preload springs, spacers, and washers are meant to maintain tension in an assembly where some slack may be present. Their capabilities can eliminate rattle, compensate for expansion or contraction of the assembly materials, or absorb intermittent shock loads. These products are made of elastic deformable materials, most commonly convoluted ductile, high-strength metal alloys which come in machined, welded, and open-ring varieties.
Door Strikes
(37 companies)
Door strikes are metal plate devices that are installed within a door jamb to stop and retain a door when closed. Multiple operational configurations are available for differing door bolt options as well as the action of the clasp mechanism and level of security.
Bore and Duct Spacers
(15 companies)
Bore and duct spacers keep pipes, conduit, and cable racking supported and evenly spaced for underground encasement.
Insulated Gate Bipolar Transistors (IGBT)
(152 companies)
Insulated gate bipolar transistors (IGBT) are bipolar transistors with an insulated gate. They combine the advantages of the bipolar transistor (high voltage and current) with the advantages of the MOSFET (low power consumption and high switching).
Door Stops and Holders
(68 companies)
Door stops and holders prevent undesired movement of doors to prevent damage to nearby objects or to keep the door ajar. There are many configurations.
Door Frames
(42 companies)
Door frames are assemblies that hang doors within structures. These include swing door, pocket door, and specialty door frames.

Insulating Varnishes and Impregnating Resins
(36 companies)
Insulating varnishes and impregnating resins are designed for applications that require a low-viscosity resin or varnish for coil impregnation or magnet wire coating insulation. The resin may infiltrate the coil or electrical device through dipping, trick
