OZBR

Block-type
Rapid Connecting Links
(fast assembly and disassembly)
acc. to DIN 22258-3
and FASING Technical Requirements

Application
For connecting round chain links acc. to DIN 22252 and flat chain links acc. to DIN 22255 In a vertical position. Due to massive and fit construction, OZBR connecting links guarantee the following: the possibility of installation in any direction of work, fast assembly and disassembly at the increased strength parameters and performance durability.

OZBR Block Connecting Links can work in sprockets that are made acc. to DIN 22256, in vertical position only.
