Better security for lower cost

This tough open style grille provides security while keeping the sense of open space. The LIGHT WAVE's sturdy construction is based on individual panels interlocked by full height hinge members. Hinge rods are completely concealed to protect them from vandalism and damage. The panels fold cleanly and positively, resulting in a smooth and easy to operate Grille.

The open concept of the door doubles in decreasing the overall door weight and increasing operation ease. As an option, LIGHT WAVES may be fabricated using steel reinforcing rods that further strengthen the grille curtain.

The LIGHT WAVE grille is a great choice for enclosing spaces that require good cross ventilation such as food court concessions. LIGHT WAVES are appropriate area dividers where strength and high visibility are needed; great for schools, sports complexes and public transit areas.

They are an ideal solution for behind glass protection, where a strong and resilient barrier is required.

Locking Options

The grille incorporates 33mm x 60mm vertical posts spaced not to exceed 3000 mm on center and located at each curve. Lead posts utilize concealed, masterkeyable cylinder operated hook-bolt with lock operable from both sides of curtain or optional thumb turn cylinder lock operable from tenant side of curtain that engages a full height wall channel. Intermediate posts provided with concealed, masterkeyable cylinder operated bottom ratcheted drop bolts with lock operable from interior or exterior side of the opening. Posts with drop bolts include dust proof stainless steel floor sockets.

The locking knobs are manufactured with heavy-duty aluminum construction.

The locking posts have a unique self-adjusting locking rod with 6 different positions of adjustments to allow for deflections in bulkheads and irregularities in finished flooring. This post allows replacing or servicing of the locking post without removing the entire door. Also lead and end posts have special softly padded astragals that prevent damage too adjacent finished such as glass or mirror pocket doors and columns.

Weight & Stacking

Grille weight is approximately 7 kg/m2. Grille support must be able to carry the weight of a fully stacked door at any point along its length.

Minimum stacking is 87.5mm/metre of opening plus 89mm per locking member (consult factory for critical project specific stack dimensions).
