Old Standard or New Standard?

New Standard Portlights superseded the old style in the later part of 1997, and they can be identified by the type of window closure.

Which New Standard?

From 1997 to June 2000 the New Standard Portlight was made with hinges and handle catches fixed to the frame with a pressing/staking process.

Staked catch Staked hinge

If you have this type of hinge, you will need to purchase a Mark 1 Acrylic.

In June 2000 the portlight was changed to use screwed on catches and hinges. The hinges and handle catches sometimes have packers under them to control the seal compression.

Screwed catch Screwed hinge

In 2008 the hinges were changed from using M4 fastenings as hinge pins to M5.

If you have screwed hinges and catches with M5 fastenings you need to purchase a Mark 2 Acrylic.

If you have screwed hinges and catches with M4 fastenings you need to purchase a Mark 2 Acrylic with an additional replacement hinge pack. You will need to swap out the M4 hinges on your existing frame in order to fit the new lens.

If you are uncertain whether or not your portlights are Mark 1 or Mark 2, please contact us.
