Spika steel gun cabinets, sized by capacity: S1 (4), S2 medium (8), S3 and S3D digital (12), SDD double door (9) and S4 extra large (15). The S2A and S3A ammunition safes bolt on as separate lockable storage.
Sizing it properly. Stated capacity assumes plain guns. Measure your longest rifle with the scope and moderator fitted, then buy a size up from what the number suggests - almost everyone fills a cabinet faster than they expect, and a rifle that has to come apart to fit gets left out. Check the internal height, not the external.
Certificate conditions. Secure storage is a condition of your firearm or shotgun certificate. Agree the model and the mounting position with your firearms enquiry officer before you buy - they will want it bolted through into solid masonry or structural timber, out of sight, and most conditions require ammunition to be held separately from the firearms. Digital locks are widely accepted but confirm it with your FEO rather than assuming.
