Containment in the event of fire - thanks to certified 1 hour fire rating

A metal door constructed from 1.2mm mild steel, paired with an intumescent seal, meets recognised fire test standards listed under BS EN 1634-1:2014+A1:2018. Certification confirms the assembly resists fire penetration for the rated period under test conditions.

Reduced risk of flame and smoke spread where services pass through walls or ceilings, helping to maintain compartmentation and satisfy safety requirements.

Discreet, serviceable finish - with a 25mm picture-frame and concealed hinge

Picture-frame trim sits around the access aperture at 25mm width and conceals the hinge mechanism, while a powder-coated RAL 9010 finish offers a paint-ready surface. The shallow 45mm depth suits installations in typical wall and ceiling cavities.

A tidy, low-profile appearance that blends with surrounding surfaces, while allowing straightforward access for maintenance without visible hardware.

Secure access for maintenance - thanks to budget lock, T-key and lock collar

A budget lock with T-key is supplied alongside a lock collar and cover, giving a keyed closure solution designed for routine maintenance access. Concealed hinge arrangement reduces tampering and keeps the closure flush.

Restricted access prevents unauthorised opening while enabling authorised personnel to reach services quickly, useful in communal buildings and managed properties.
