To mount the Divator MkII, Visor assembly.
Made from robust, GRP (Nylon 12) and slighlty heavier than the grey ones approved for Divator, Spiromatic and Sari masks, the frame halves are easily fitted, inter-locating on key ways, to clamp the visor firmly in to the mask, using stainless steel screws (M3 x 25), washers and spacer set {not included}
In the water, mask weight is not as critical as is required for surface approvals and this version is specifically for extra abrasion resistance - about 25 gms (1/3) heavier than 336 190 012, the standard ; mask abrasion being a critical cause of wear in commercial diving.
This frame half set may not be interchanged with 336 190 012 unless as a complete pair because the frame half lugs are moulded in opposite fashion to these items, which are otherwise similar. Both part numbers are approved for use on the Divator but this, slightly heavier version is not approved for use on the Spiromatic or sari masks of the "family", where light weight is critical to function.
Tools needed: 2 mm hexkey, small pry-bar (Flat blade screw-driver will do) and soapy water. Details are published in the Divator, User Manual, issued with every mask.
