Speedy-fix collars are made from AISI 31L stainless steel ribbon (X5CrNi1810 1.4301 UNI EN 10088-1). They are composed by a shaped support, which base has a threaded nut, and by a half moon shaped strip with two fastening screws that lock the conduit in place. The base units are available with a 6x10mm slot, the burr-free edges mean they can be installed without scratching the conduit. The screw-free system means they can be installed and the conduit inserted in place without the use of tools, thus drastically reducing the assembly time required. Screws and plugs must be ordered separately.
