This formula is based on a storage unit with an inset door. Allow for any gaps to ensure positioning is as accurate as possible.
First, find out the following dimensions:
X1 & Y1 = gaps along the horizontal and vertical axis, respectively.
Z1 = Board thickness of door.
Y = Your own choice of vertical positioning of Flexlock.
If X1 = 1 mm, Y1 = 1 mm, Y = 10 mm and Z1 = 16 mm, we get:
Positioning of Flexlock
Y = 10 mm
X = 7 – 1(=X1) = 6 mm
Positioning of lock plate
Y2 = 10(=Y) + 1(=Y1) + 11 = 22 mm
Z = 16(=Z1) + 38 = 54 mm
Note: Carefully clean the surface where the mounting plate is to be fitted using the wet wipe supplied with it. Alternatively, use an isopropyl alcohol/water mix or heptane.
