Shot straight up from directly beneath a semi-circular steel fan top light over a doorway, morning sun behind it, the seven radial bars silhouetted hard black against a blown-out white sky.

Top lights
A fixed glazed panel above the door for tall Georgian and Victorian openings and arched heads, so the door stays a normal height.

- Square, segmental or semi-circular heads

The whole top lights square on and filling the frame, in the square head configuration, shot level in flat overcast light against a plain wall so the proportion and the frame-to-glass ratio can be read without perspective. Unit at 3600 mm.
3:4
Close detail of the meeting line at eye level in raking light, tight enough that the joint and the seal are legible, with the background thrown out of focus.
1:1
The hand-level detail: no moving hardware photographed in use on the 213 ral colours finish, close enough to show the surface texture and the fixing, with a hand on the handle for scale.
4:3
From inside the room looking out through the top lights, the unit open where it opens, late afternoon light on the floor, so the product is seen the way it is lived with rather than the way it is sold.
16:9
The top lights at dusk from outside, closed, the room lit behind the glass, so the finish and the glass line read against the light.

Specifications & options
Top lights
Description
Openings taller than 2700 mm need a transom. A taller leaf loads the hinges and slows the door; a top light adds the height in glass instead. The transom reads 55 mm and lines through with the side panel heads where both are specified. Square, segmental and semi-circular heads are all welded, with radii from 600 mm. Over a Secured by Design door the top light has to be laminated on both leaves, or the rating stops at the transom.
Specify it when
Georgian and Victorian openings over 2700 mm tall, and any arched head, where the door itself should stay a normal height.

Shot straight up from directly beneath a semi-circular steel fan top light over a doorway, morning sun behind it, the seven radial bars silhouetted hard black against a blown-out white sky.
1:1More in security
Head-on at eye level, a black steel entrance door closed in a stock-brick London terrace, late afternoon side light raking across the powder coat so the weld lines and the 40 mm frame face read hard against the sky reflected in the glass.

Steel entrance doors
Interior view from a dark hallway looking out through an equal steel pair standing half open onto a bright garden, camera low and centred on the 80 mm meeting stile so the passive leaf shootbolt and the drop-down threshold seal both sit in frame.

Single and double doors
Three-quarter exterior view at dusk of a steel entrance door flanked by two narrow glazed side panels with the hall lit inside, framed so the 55 mm mullions cut the warm interior into three even vertical bands.
