Concentric Security offers a patented mechanical attachment system manufactured by GlassLock for use with fragment retention film to protect building occupants from glass and blast hazards.

This unique mechanical attachment system is attached to the interior of the existing window frame and anchors the window film to the window frame. In the event of an explosion or glass failure the GlassLock system will ensure the entire window remains attached to the window frame and mitigates the danger of flying shards of glass or the entire pane of filmed glass.

This effective system allows buildings to be retrofitted with minimal disruption to building operations while meeting tight budgets for blast and glass hazard mitigation. Installation of a mechanical attachment system saves time and money.
