Weatherproof project enclosure with clear top

The Adafruit enclosure protects electronics in a sealed ABS body with a polycarbonate lid rated IP66. M4 threaded bosses inside the case accept standard screws for board mounting. It suits hobbyists and engineers who need a durable, reusable housing for outdoor or damp environments.

IP66 rating defines dust and water limits

The IP66 seal blocks dust ingress and withstands powerful water jets from any direction. It is not rated for continuous immersion, so the box should not be submerged. The clear lid allows visual inspection without breaking the gasket, but it does not transmit wireless signals differently than opaque plastic.

Simple assembly with reusable screws

The captive screws open and close repeatedly without stripping the plastic threads. M4 hardware fits the internal bosses directly; no self-tapping screws are required. Over-tightening can deform the gasket and reduce sealing performance, so hand-tighten only. No tools beyond a screwdriver are needed for installation.

Questions about this item

Which enclosure size should I pick for my project?

This model measures 125mm x 175mm x 75mm overall with 70mm internal height; choose it when those dimensions fit your board and wiring.

What does the IP66 rating mean once the box is installed?

IP66 means the gasket-sealed enclosure resists powerful water jets and dust ingress when the clear polycarbonate lid is screwed down.

What mounting standard do the internal bosses use?

The built-in bosses are tapped for M4 threads, so you can secure PCBs or rails directly with M4 screws.
