Key Features & Typical Use
Compact Footprint
The dimensions of the HM-D33 at 95 × 120 mm provide it with the ability to fit UK sockets with minor wall footprint – being well-suited for narrow wall ends, utility corners, and other locations that require smaller boxes.
ABS + PS Build
The plastic base of the box makes it stable, whereas the PS cover ensures a perfect closing after many usages. No gaskets to maintain and no elements that could get misaligned.
Screw-Mounted Simplicity
Thanks to an easy assembly with screws on the base, the HM-D33 is securely affixed to plaster, wood, and cement sheet substrates, making it suitable for utility areas, basements, and garages.
Three Finishes
White for conventional wall surfaces, transparent to disappear, and black transparent for the frame look—one SKU, three options of interiors.

Frequently Asked Questions
What is an indoor waterproof box?
An indoor waterproof box is a type of cover used to protect electrical sockets from dampness and water splashes. This can cover sockets installed in damp places such as garages, basements, and utility rooms.
Where does the HM-D33 fit best?
Indoor locations where the risk of splashes is present but not constant – utility corners, garages, basements, storage rooms, and covered external passageways. For areas where there is constant splash, you need to choose an IP55 rated waterproof box, such as HM17.
How is the HM-D33 mounted?
The devices are mounted on the surface of the wall using screws put through the base which allows for easy installation on walls. `
What finishes are available?
There are three available colors of boxes for electrical sockets, including white, transparent or black transparent respectively, with the last two allowing you to see the switch in the socket through the closed cover.
