The problem
Opening the door defeats the screen
- 01
Opening the door to hand something over
Every time a door opens to pass a parcel out, the protection stops being protection.
- 02
Cash crossing the counter
Cash and valuables go through a tray, never hand to hand.
- 03
Serving when the building is closed
A hatch lets staff serve out of hours without opening up.
- 04
Bulky items
Large parcels need more than a tray, which is what bulk transfer units are for.

The range
The range, with tech sheets
Made to size in our Edenbridge workshop. Each page carries the standards, the dimensions we work from and the tech sheet.
Which tray do we need?
It follows what crosses the counter: documents, cash packets, or items that need speech alongside them. On a bullet-resistant counter the tray is specified to match the glazing.
Can a hatch take parcels?
Yes. The vertical hatch is designed for passing large or small packages without putting staff in danger.
Can these go into an existing counter?
Often, yes. It depends on the counter construction and the opening. We check at survey.
Do you have technical sheets?
Yes, there is a tech sheet for every product in the range. Ask and we will send the ones you need.
Why MerFen
One firm makes it, fits it and keeps it working
Most installers fit what a manufacturer sells them. We make the physical side ourselves, so the specification starts with the site.
