Ref. : FBLP.01. BC.04 / FBLP.01. BC.05Clasp FBLP.01. BC.04 is in the same spirit of construction as the previous ones. It engages laterally in two points and accidental disengagement is almost impossible. It should be noted that the construction of clasp FBLS.01.BC.05 has a difference in the blocking point. Its construction is slightly more complicated.
