Slack shock cord can make tent poles awkward to assemble even when the metal or fibreglass sections are sound. Replacing the elastic may restore orderly handling, but start by checking that the pole itself has no cracked sections, damaged ferrules or missing end fittings.

Record the assembly before removing anything
Lay the pole out in a clean space and photograph the complete sequence. Mark sections in order with removable labels, noting different lengths, curves, hubs and end pieces. Outwell’s cord-repair guide emphasises preserving the correct section order before rethreading.
Inspect how the old cord is anchored. Some ends unscrew or release; other designs use fittings that need model-specific instructions. Do not force a hub apart because a simple straight-pole tutorial uses a different arrangement.
Match the cord to the pole
Check the required diameter and available length. The MSR Shock Cord Replacement Kit supplies 3.5 mm cord, making it a specific specification rather than a universal fit. The MSR kit on Amazon UK is worth considering only if that diameter and kit length suit your assembly.
Ordinary string lacks the elastic behaviour required for the normal assembly. Conversely, a thicker elastic is not automatically an upgrade if it binds inside a narrow ferrule. Obtain the pole maker’s recommendation where the original specification is unclear.
Thread and tension methodically
Follow the supplied instructions through the numbered sections, retaining the correct end fittings. Keep the working length under control so it cannot disappear into a partially assembled pole. Check the intended knot and anchoring method before trimming anything.
Use the manufacturer’s tension guidance rather than a universal percentage of pole length. The cord should assist assembly without putting unnecessary strain on fittings or making the pole difficult to fold. Avoid using the old, stretched cord as the sole guide to the new finished length.
Test assembly and packing
Seat each joint fully by hand and check that the sections remain in the correct order. Do not let them snap together at speed. Fold the pole using the maker’s recommended sequence, then assemble it again to confirm that the cord moves and retains the sections properly.
Pitch the tent in a controlled setting before the trip. A successful cord replacement improves handling, but it does not strengthen a damaged pole segment. Replace or professionally repair any structural damage separately, and keep the model and cord specification in your maintenance record.
A cracked section needs a different response: read our tent pole repair-sleeve guide. Our aluminium vs fibreglass pole comparison explains why a same-length replacement is not automatically suitable.
