For maximum poster security, our locking snap frames feature a built-in allen key lock that prevents unauthorised access. The sides open sequentially, with the lock positioned on the short profile — one lock on smaller sizes, two locks on 20" x 30" and above.The robust 32mm profile makes these our most sturdy snap frame, particularly on larger sizes. We consider these more secure than our vandal-resistant frames, making them ideal for high-security environments such as transport hubs, public buildings, and outdoor locations.A special allen key is supplied free with every frame.Specification Strong 32mm aluminium profile Security allen key lock (free key included with each frame) Sequential side opening Anti-glare protective cover sheet included Available in silver anodised and black Mitred corners 1.5mm rear plastic panel Wall fixings included Individually boxed Sizes & Dimensions A4 — 210 x 297mm | Viewable: 190 x 277mm | Overall: 240 x 327mm A3 — 297 x 420mm | Viewable: 277 x 400mm | Overall: 327 x 450mm A2 — 420 x 594mm | Viewable: 400 x 574mm | Overall: 450 x 624mm A1 — 594 x 841mm | Viewable: 574 x 820mm | Overall: 624 x 871mm A0 — 841 x 1189mm | Viewable: 820 x 1168mm | Overall: 884 x 1232mm 20" x 30" — 508 x 762mm | Viewable: 488 x 742mm | Overall: 551 x 805mm 40" x 30" — 762 x 1016mm | Viewable: 742 x 996mm | Overall: 805 x 1059mm 60" x 40" — 1016 x 1524mm | Viewable: 996 x 1504mm | Overall: 1059 x 1567mm
