Letterbox Block Numbers
These stainless steel block numbers are designed to be mounted on a sandstone block, so have stainless steel bolts mounted as studs on the base.
Holes can be drilled then a spot of liquid nails applied and push the studs in to mount.
Each numeral of #19 is approximately 180 mm high, and the sides are 40 mm deep. It looks great mounted next to the red letterbox.
