Tectura Designs' Lok Down unit is made to secure your roof paver ballast or your balcony/plaza/promenade paver areas.
The unit is a base with nubs to align the paving unit with ease. A top plate, made to match or contrast with the pavers, fits into a recess, allowing for a flush walking surface.
Colored bolts tighten the system together for a total rafted paving system.
