Ref. : FBLP.01.BH.15S / FBLP.01.BH16S / FBLP.01.BH17S / FBLP.01.BH.18S In the design of models FBLP.01.BH.13S and FBLP.01.BH.14S the security is elaborated in metal plates and not in threads like security in 8. These clasps, also the FBLP.01.BH.15S, ask for more work. They are used for quite heavy bracelets and necklaces. Clasp FBLP.01.BH.16S has a very good coefficient 3 F (see the note: coefficient 3F). It is easy to make, easy to handle and safe in use. Clasps FBLP.01. BH.17S is also with safety in the push-button. The difference with the FBLP.01.BH.16S is in the box construction. See file 3D. FBLP.01.BH.18S is a clasp of the 80s. It takes again the theme of construction of other clasps of the beginning of the 19 centuries. NOTE : Classification of clasps 3F : Fonctionnalité - Fiabilité - Faisabilité( in french) Functionality - Reliability - Feasibility. The scale is from 1 to 5.
