Unique-Bargains 11pcs Plastic Junction Box 40x20x11mm Conduit

11-piece plastic junction box kit

This set supplies eleven black plastic enclosures sized at 40 x 20 x 11 mm for protecting small electrical connections. Each box weighs roughly four grams, giving a total pack weight of 45 g. The sealed design aims to keep moisture and corrosion away from sensitive components in harsh environments. Hobbyists and installers can use them for automotive wiring, sensor housings or low-voltage project enclosures.

Sustained environmental protection

The waterproof seal is intended to maintain its barrier during continuous exposure to damp or corrosive conditions rather than only brief splashes. The rigid plastic shell resists degradation so the internal instruments stay shielded over long service periods. No active cooling or moving parts are involved, so reliability depends on the seal integrity and material stability. The enclosures remain passive protective shells throughout their operating life.

Upgrade from open terminal strips

This kit replaces unsealed terminal strips or improvised boxes that offer no ingress protection. The jump is worth it when wiring must survive persistent moisture, dust or chemical vapour without additional potting. Builders who need larger internal volume, metal shielding or pre-drilled cable glands will not find those features here. The boxes arrive solid, requiring any holes or cut-outs to be made by the user.
