Security Devices

The Tufnut Works offers standard and custom security products that use a variety of adhesive steel plates, padlocks, cabling and fixed anchors to protect computers and peripherals from theft. The basic component is the Tufnut, a pyramid-shaped nut that can be fastened with regular tools.

New Straightlock Systems lower costs by allowing you to add standard P34, NP6 or NP3 plates (without loops attached) to secure additional equipment. The KBA Keyhole Bolt Assembly anchors the system right to the desk using a Tufnut (no padlock required).

To prevent tampering with internal components of a computer, replace two or more case screws with Caselok adapters. A cable passes through the adapters to keep the machine intact and locked down. In the last decade, more than 100,000 Tufnut systems have been installed in schools.

The firm originally developed the Tufnut to deter traffic sign theft, a common problem in areas surrounding schools. The schools themselves began purchasing the nuts to secure signs and, later, office equipment. The Tufnut Works, Tesuque, NM, (800) 227-0949,

The Lock-Down Station from SECURITYWARE comprises four factory-assembled steel components that work together to secure portable computers. An adhesive plate bonds to any surface; a base plate attaches to the adhesive plate to prevent its removal; a steel cover is bolted to the base plate; and a steel door locks into the cover and base plate to restrict access to the station's contents.

Those with a key simply unlock the door, take the computer out and turn it on. The sturdy steel case enables placement of a monitor on top without sacrificing desk space. The monitor and other peripherals also can be secured to the Lock-Down Station. SECURITYWARE, Inc., San Diego, CA, (619)
