Slimport Porthole Windows

Slimport Porthole Windows

The ZEROplus top selling porthole window is Slimport: a circular vision frame for installation in doors, walls and partitions. This round window frame is suitable for four different door cut-outs: 250mm (SP250), 350mm (SP350), 450mm (SP450) and 550mm (SP550).

With no visible fixings on the corridor side, the Slimport is a good-looking porthole. It features countersunk holes in one side of the bevel return only, while its 25mm screws pass through the door cut-out and fix internally, so the porthole window looks sleek and smart.

DOOR AND GLASS THICKNESS

Slimport porthole window frames are available to suit the four most popular door thicknesses of 40mm, 44mm, 50mm and 54mm with a tolerance of ±2mm. The glazing pocket is 10mm wide (±2mm in relation to the door thickness) to accommodate 6mm-thick glass and appropriate glazing tape. If you have other door and glass thickness combinations please contact us for more information.

FIRE TESTING

Slimport porthole windows have been fully fire-tested in timber and steel doors.
