This double sheave block for changing line is a optical fiber cable stringing equipment, these nylon rollers have the best Nylon made, with the special surface treatment, so it is very strength and smooth, after millions times applied, it still can keep this situation, with the least friction.
This device is specifically designed for replacement of an existing ground wire (G.W.) with OPGW (Optical Grounding Wire).
 It is composed by two galvanized steel half frames linked by a ring with a swivel plate.
 In each frame are fitted:
 1. one grooved nylon roller with two ball bearings
 2. three nylon plates to guarantee the OPGW protection
 One side of each frame can be easily opened by a knurled nut.
The frame have been designed in order to avoid any contact of the OPGW with the steel part.
