Splinting a broken tent pole

A tent pole is mainly loaded in bending: it is fitted in a curve, and wind presses against the tent on top of that. At a break the pole can no longer carry this bending – it kinks there. A splint bridges the break and takes over the bending, so the force runs through the splint rather than the break.

For this to work, the splint must reach well beyond the break on both sides. A splint that is too short acts like a new hinge and levers at its ends. The longer and stiffer the splint and the tighter it is fixed, the better the repair holds.

A repair sleeve works the same way, just all round from the outside: it surrounds the pole and keeps the two broken ends in line. Because it is round, it slides through the tent's pole sleeve more easily than a splint tied on to one side.

First carefully pull the pole out of its sleeve or undo the clips. Look at the damage calmly: is the pole only bent, or properly broken? You can carefully straighten a bent aluminium pole as far as possible; it stays weakened, though, and still gets a splint or sleeve.

For the sleeve, take the pole apart at the nearest joint, slide the sleeve over the section and centre it over the break. Then wrap both ends of the sleeve tightly with tape. Round off the edges of sleeve and tape with a few extra turns so nothing catches on the fabric.

When putting it back in: slowly and without force. A splinted pole is thicker and stiffer; if you force it through the sleeve, it can damage the fabric or shift the repair. Afterwards, add extra guylines and check the repair the next morning.

A tent repair kit should contain a matching repair sleeve (many tents come with one) and tape, ideally strong fabric tape. A tip: wrap a few metres of tape around a trekking pole or water bottle so you always have it with you without carrying a whole roll. A multitool and a pair of gloves help when working on splintered poles.

Without a sleeve, a straight metal peg, a section of trekking pole or a straight, firm piece of wood can serve as a substitute splint. What matters is that the splint is straight, stiff and long enough. Lay it lengthwise along the break so it sticks out well on both sides, and wrap everything tightly with tape.

If it is not the pole but the shock cord inside that snaps, that is usually no drama: the sections can be joined one by one and secured at the joints with tape. Pitching and striking become a little more fiddly, but it holds.

Fibreglass and carbon poles splinter into fine, sharp fibres when they break. These can get into the skin and are unpleasant. So wear gloves, do not strip splinters with bare hands and cover the break completely with tape. On carbon poles an emergency repair has only limited strength.

A splinted pole withstands less than an intact one. In strong wind, add guylines, pitch the tent lower or find a more sheltered spot. In severe weather in an exposed position it is often wiser to seek shelter or retreat rather than repair the tent in the storm.

With several breaks in the same pole the method reaches its limits. Then think about whether the tent still provides safe shelter, and work out an alternative for the night.

A repair on the move is always temporary. At home the broken section should be replaced. That is often possible through the manufacturer or a specialist shop, and many sections can be swapped individually without needing a whole new pole set.

Aluminium poles often bend first when overloaded, before they break. Fibreglass poles tend to break suddenly and splinter. Knowing this, you can check the poles specifically for kinks and fine cracks after a stormy night.

Prevention helps most: when pitching, always push the joints fully together, not halfway, and do not let the sections snap together wildly. Half-seated joints are a common place for breaks. That is why mountaineering handbooks count repair materials for tent and gear as basic equipment.
