Preston F/I Unit Mounting Bracket
One 1/4” UNC and one 3/8” UNC mounting point
DITs can bolt the unit securely in place
This is an attachment which screws onto the Preston F/I unit to give you a solid mounting point to bolt into, using either the 1/4” or 3/8” position.
Fix the bracket to the F/I unit by replacing the four 4-40 x 3/8” countersunk screws with slightly longer 1/2” ones.
The bracket’s mounting plateaux is 25mm wide x 60mm long and so is ideal for ‘Cine Lock’ QR type attachments.
To buy this bracket
To complete the bracket you will need;
One 1/4 UNC half-height hexagonal nut (only a 4mm high half-nut will fit)
One 3/8 UNC half-height hexagonal nut (only a half-nut will fit)
In the UK, I have found Westfield Fasteners a good source for UNC nuts and bolts and the links above are to their site.
