Vision kits



Vision kits are offered in 3 different designs. These designs can be classified as follows:


  • Overlapping vision kits: For standard applications, they overlap the door faces.

  • Inserted vision kits: Inserted between the door faces, they prevent conflict with finish hardware.

  • Full flush seamless vision kits: Seamless and flush with the door face, these kits are commonly used in sanitary applications, for esthetic design or where security is important.


The sandwich overlapping vision kit, with 2 components coming together from each side of the door, is the most commonly used in our industry. This vision kit offers a nice design and the corner sections are welded.

Other standard overlapping vision kits, with 8 distinct components, are not recommended. Their design is not esthetically pleasing and the corner sections are not welded.

Channel reinforcements in the cut-out perimeter are required on full glass and half glass doors to preserve the structural integrity of the door.
