Gaffer Duct Tape 50mm / 75mm / 100mm

Duct tape is one of those things every trade van carries, and for good reason. This gaffer tape sticks to most surfaces, tears cleanly by hand without scissors, and holds up in damp or dusty conditions where lighter tapes give up. Whether you call it gaffa tape, gaffer tape, or duct tape, it is the same reliable product — and this range covers three widths and seven colours so you can grab the right size and shade for the job rather than making do.

The tape is available in 50mm, 75mm, and 100mm widths. The 50mm roll is the go-to for most general tasks: cable management, temporary repairs, labelling, sealing bags of materials on site. The 75mm width gives you more coverage on larger surfaces or ductwork joints. The 100mm roll is best when you need a solid bond across a wider area, such as sealing vapour barriers, protecting surfaces during a job, or bundling materials together for storage or transport.

Where Duct Tape Actually Earns Its Keep

On a building site, this tape gets used across almost every trade. Electricians use it to bundle cables and secure conduit temporarily. Plumbers reach for it to seal around pipe penetrations or protect fittings during a pour. Roofers use it on vapour control layers and temporary weatherproofing. Painters use it to protect surfaces and mark out areas. General builders tend to use it for everything else — because when something needs holding together until a proper fix goes in, duct tape is nearly always what you grab first.

The colour options are more useful than they might seem. Silver is the standard, and it blends well on ductwork and metalwork. Black suits cable tidying and anything where appearance matters. The coloured options — blue, green, red, yellow, and white — are handy for colour-coded labelling, organising equipment, or marking out different services on a job. On complex sites where multiple trades are running alongside each other, being able to colour-code your cables or temporary fixings saves a lot of confusion.

Bulk Buying and Trade Pricing

If you are buying duct tape in volume — for a large site, a supplies room, or regular restocking — bulk deals are available. Contact us directly for pricing on larger quantities. At £1.75 a roll, the standard price is already fair, but if you are ordering in quantity it is worth getting in touch before you add to the basket.

This is not a specialist product requiring a lengthy explanation, but it is one that benefits from being stocked in the right widths and colours before a job starts rather than improvised mid-task. Getting the correct duct tape width for the application makes a noticeable difference to how cleanly and securely the tape holds — 50mm is not always enough, and 100mm can be unwieldy when 75mm would have done the job neater.
