Sealing the cable entry

A cable gland seals the point where a cable passes into an enclosure or back box, closing the gap so moisture and dust cannot reach the connection inside. It is a small part that does important work, keeping a junction box or fitting weathertight where the cable goes in. Without one, the hole a cable runs through is the weak spot that lets water track into the connection.

Weatherproof M20 nylon glands

This range covers M20 nylon glands in black, carrying an IP66 weatherproof rating that suits outdoor wiring and damp settings. The nylon body resists corrosion and grips the cable as it tightens, forming a tidy seal that holds up where an unsealed entry would let water track in. Black nylon also stands up to sunlight and the knocks of outdoor use better than many alternatives.

Where they earn their place

Glands like these belong on garden wiring, outbuildings, exposed junction boxes and any run where the connection sits outside or in a damp spot. Pairing them with weatherproof boxes keeps the whole connection sealed from cable to enclosure, so there is no point along the join where water can get a foothold.

Fitting them in

A gland fits into a prepared hole in the box or enclosure, with the cable passed through before the body is tightened down onto it. As it closes, the seal grips the cable and shuts off the gap around it, so the entry stays as weathertight as the box itself. Getting the hole size right and seating the gland squarely is what makes the seal hold over time.

Supplied in bulk packs

These glands come in packs of ten, giving you enough to fit a run of junction boxes in one go rather than ordering them one at a time. That suits a larger outdoor job or keeping a few spares on the shelf for repairs, so a damaged gland can be swapped without holding up the work. Free UK delivery over £99, worldwide shipping.
