SlateSpacer™ is an inexpensive, concealed, stainless steel spacer that rests beneath the end of each roofing slate.

Broad, flexible and very thin (1.2 mm (less than 1/16")), SlateSpacer™ offers the benefits of separating slates without creating breakage or weather entry problems.

SlateSpacer™ works on nailed or hooked installations, on open or closed roof structures. It installs quickly with a simple insert-and-twist motion (no fasteners required).
