I acquired one REI from Recreational Equipment Inc. in 1985, and a second from Duane Frerichs in 2009.
The REI is 43 mm. long, 51 mm. wide, 15 mm. high, and weighs 39 g. It has two slots that are 32 mm. long.
One side is stamped with the REI logo.
Functionally, the REI is a fairly standard "Sticht" type belay device. Although smaller than most, it is large enough to handle, and has some margin for wear at each end. Being so small, it has little heat absorption capacity. The Chouinard 11/11 is similar but designed for 9 mm. rope.
