ABSTRACT:
The "Spider Thread" is a device which enables a person to descend from a point, much like a spider coming down from a ceiling. Its main part is a reel on which a long, flat strip (preferably steel) is wound. Said reel is placed between two plates that form the body of the device, and all parts are held together by a center bolt and a wing nut which when tightened press the plates against the reel and provide a brake that controls the rate of the descent. When used, the strip is first securely fastened or hooked at the starting point. The user must wear a harness which he connects to a hook provided for that purpose at the above mentioned plates.
