<p>Duct tape is a cloth-backed, rubber-adhesive tape that sticks to almost anything, seals gaps, patches tears and can be torn to any length by hand. It has been a staple of emergency kits, tool bags and glove boxes for decades because it solves so many different problems with one roll: taping over a cracked tent pole, sealing a leaking pipe, patching a punctured tarp, splinting a finger, or bundling loose gear together. A single roll typically runs from around 3 to 50 metres depending on the size bought, and UK prices generally sit between £3 and £10 a roll.</p>
<p>Zip ties (cable ties) are plastic strips with a ratcheting head that pull tight and lock, giving a fast, permanent-feeling bind between two points. They are the go-to for securing loose cables, lashing a tarp to a frame, fixing a wobbly gate, bundling firewood, or making an improvised repair where something needs to be held firmly rather than sealed or patched. A pack of 100 mixed-size ties typically costs £5 to £12 in the UK, working out to pennies per repair, and they take up almost no space in a kit.</p>
