Standard radius cornered outer frame profiles

Standard bonded installation outer frame

The hopper window consists of a drop back vent(s) above a fixed glass suitable for either rubber gasket mounting to the vehicle or bonding.

There are a number of outer frame profiles available with two of the most popular referenced for typical radius cornered requirements plus a typical bonded installation profile.

Depending upon the overall width of the window either one or two vents can be present and are opened by a passenger pulling the extruded fingergrip profile running along the top of each vent. Alternatively an unframed vent can be supplied with a handle mounted through the glass.

The vents are held in either the fully open or fully closed position via tensioned springs located within the horizontal crossrail.

The opening force can be fine tuned by the addition/deletion of springs but care must be taken as the spring pressure also provides the necessary compression upon the weatherseal.

4mm or 5mm thick toughened glass is the usual glazing medium for hopper windows but bespoke profiles do exist for thicker glass requirements. PLP’s Engineering team would be delighted to discuss your individual needs and create a hopper window solution for your requirements.

Furthermore PLP are able to offer a continental style hopper window exhibiting a cut-out in the glass.
