How to Tie the Tarp Corner Quick Release
The Tarp Corner Quick Release is the knot to use when a tarp's grommet has torn out and you still need to anchor that corner. You bunch the bare fabric into a fold, tie a Slipped Sheet Bend around it, and the corner is a tie-out point again — no hardware, no repair kit. One pull on the tail releases the whole thing instantly.
Why Learn the Tarp Corner Quick Release?
Because grommets fail in the field, and this is the one-knot fix that works on bare fabric. The trick is simple: the bunched corner fabric itself stands in for the second rope of a sheet bend. Bear Essentials' way to remember what you've really tied: the bunched fabric IS the second rope — so the tarp's fabric, not your cord, sets the limit on how hard it holds. That single idea tells you both when this knot shines (quick field fixes) and when it doesn't (anything load-critical or left unattended).
Common Uses
Camping and Bushcraft
- Grommet-failed tarp corners: anchor a guyline to a tarp corner when the grommet is torn out or missing, by bunching the bare fabric into a fold and tying the slipped sheet bend around it — the knot's core, name-defining job.
- Tape-loop tie-outs with easy removal: attach a guyline to a tarp's tape loop or tie-out tab with the quick-release finish, so the line comes off with one pull when you break camp.
Historical
- Ship and tent rigging (period use): Ashley recorded the slipped sheet bend as handy "when launching and rigging" and noted its use on circus tent gear — historical applications, not a modern load-rating endorsement.

Notable Features
- Works on bare fabric: no grommet, clew, or fixed eye needed — the bunched corner fold is the anchor point.
- Instant release: a single pull on the protruding tail withdraws the tucked bight and spills the knot — it never jams under working tension.
- Minimal cord used: a single turn and a slipped tuck, in keeping with the sheet bend family's low rope consumption.
Similar Knots
Slipped Sheet Bend vs. Tarp Corner Quick Release
These are the same underlying structure in two framings, not two different knots. The general slipped sheet bend joins two cords; the Tarp Corner Quick Release ties your cord to the tarp's own bunched fabric, which plays the part of the second rope. Reach the general form when the join is cord-to-cord; use this application when the join is a bare tarp corner.
Sheet Bend vs. Tarp Corner Quick Release
The plain sheet bend, tied onto an intact grommet or fixed eye, divides the load across both legs and snags less — more secure than bunching bare fabric with the slipped form. The slipped tarp-corner form trades that security for one-pull release. If the grommet still exists, tie to it directly; relatives like the Tucked Sheet Bend offer other security trade-offs on the same base structure.
Security Level
Low by design. This knot deliberately trades holding security for instant release — Robert Birch's sheet bend review puts it plainly: slipped and toggled versions are "easily made for quick release at the expense of security." It's reliable under constant working tension, but it is not a set-and-forget hold. The sheet bend family has a documented tendency to slip in smooth synthetic cordage, so a grippy line such as a sheathed bushcraft paracord gives the nip more to bite.
Downsides
- Fabric is the weak link: holding power depends entirely on the tarp material — a weak or worn tarp may tear no matter how well the knot is tied.
- Creeps when slack: like the rest of the slipped family, the tucked bight is held by the nip alone and can work loose without steady tension.
- Not the crowd favorite: in practical tarp-corner discussions the taut-line hitch family dominates; this sheet-bend approach is the niche answer for the specific grommet-gone problem.
History
The structure is Ashley's slipped sheet bend, published in The Ashley Book of Knots (1944) with "launching and rigging" and circus tent gear as its named uses — tarps appear nowhere in his entry. The modern tarp-corner framing comes from Robert Birch's 2020 review Sheet bends and alternatives, which illustrates forming the bight in bunched tarp fabric when no grommet or clew exists. Background on the wider family is well covered in Wikipedia's sheet bend article.
How to Tie the Tarp Corner Quick Release
Step 1
Bunch and fold back the tarp's corner fabric into a compact fold. This fold stands in for the bight — the folded second rope — of a normal sheet bend, and the bight always belongs in the larger, stiffer material: here, the fabric.
Step 2
Take the cord's working end — the end you're tying with — up through the fabric fold.
Step 3
Wrap the working end around behind both legs of the fabric fold.
Step 4
Instead of tucking the full end back under the turn, tuck a bight — a doubled loop — of the cord under it. That doubled loop is the slipped, quick-release element. Snug the turn down onto the fabric right away; the fold has no fixed shape until the cord holds it.
Step 5
To release, pull the protruding cord tail. The tucked bight withdraws and the knot spills instantly.
If a step is hard to picture from words alone, the Knot IQ app animates this exact tie move by move — useful here because no traditional book diagram shows the fabric-bunching step. It pairs well with practicing on the cords in the Camping Knots edition knot tying kit before your tarp actually needs the fix.
FAQ
Can I use this knot if my tarp's grommet is torn out?
Yes — that's its core purpose. Bunch the bare corner fabric into a fold and tie the slipped sheet bend directly around it.
Is this knot strong enough for a storm-damaged roof or other critical, unattended use?
No — treat that as a critical application needing expert-selected rope, knots, and hardware, not a deliberately quick-release-oriented knot.
Is this the same knot as the Slipped Sheet Bend?
Structurally, yes — same underlying form. This page covers the tarp-corner fabric application specifically; the general rope-to-rope version has its own guide.
Important Notes on Safety
Do not use the Tarp Corner Quick Release for critical or unattended applications under potentially adverse or shifting loads. Birch's review specifically names securing a tarp on a storm-damaged roof as a job requiring expert-level selection of rope, knots, and equipment — and cautions against slipped or toggled bends for such use without checking security under load first. A knot built to release with one pull is the opposite of what an unattended, safety-critical anchor needs. Two common mistakes to avoid: tucking the full end through (you get the plain, non-releasing sheet bend), and forming the bight in the cord instead of the fabric (snag-prone and less secure).
