Who it suits
Is it right for you?
Great for
- Carp anglers who use crimps or neat looped connections. The covers tidy and protect the connection while giving the finished rig a cleaner profile.
- Anglers fishing over weed, silt or chod. The tapered shape can help cut down snagging, while the tungsten content helps pin the rig closer to the bottom.
Maybe skip if
- Anglers fishing ultra-minimal, tiny rigs. The cover adds some bulk around the connection and may be more tackle than your presentation needs.
- Anyone wanting a big value pack for constant rig tying. Ten covers is handy, but regular rig builders may find the pack disappears fairly quickly.

Quick verdict
A cracking little rig tidy-up
These are dead handy for covering crimped loops, knots and other rig components without adding loads of faff. The tapered shape should slide neatly over line, while the denser tungsten material helps keep things pinned down.
They’re not essential for every rig, but they make a lot of sense when you want a neater finish, better protection around a connection or a low-profile presentation over a choddy or weedy bottom. Proper useful terminal tackle, mate.

The tungsten-impregnated TPE, ribbed finish and supplied applicator point to a well-considered little rig accessory.
The tapered shape, two bore sizes and added density give it a useful job across several rig situations.
It won’t transform a rig, but reducing snagging and keeping connections tidy can help preserve a cleaner presentation.
The wire applicator should make fitting much less fiddly, though choosing the correct end still matters.
Ten covers offer useful specialist tackle, but the pack may feel small for anglers who tie rigs regularly.

The full rundown
Everything you'll want to know about the RidgeMonkey Rock Bottom Crimp & Knot Covers
There’s always one bit of a rig that looks a bit scruffy, isn’t there? A crimped loop, exposed knot or chunky connection sitting there like it’s asking a crayfish to have a go. The RidgeMonkey Rock Bottom Crimp & Knot Covers are made for tidying up those jobs. Small, simple and aimed squarely at the angler who likes a neat end tackle setup.
You get ten covers in the pack, supplied on a wire applicator. That applicator is a proper useful touch because these things are tiny, and tiny bits of terminal tackle have a habit of vanishing into the grass, the rig box or somewhere under your bivvy bed. It should make sliding a cover into position less of a fiddle when you’re tying rigs at home or sorting a last-minute change on the bank.
Each cover measures 15mm long, 5mm wide and 5mm high, with a stated weight of 0.3g apiece. That’s not a massive lump of tungsten, but it’s enough to add some useful density around a knot or crimp. If you’re trying to keep a rig sitting low and tidy, that extra bit of weight can be handy rather than just dead ballast.
The material is tungsten-impregnated TPE, giving the covers a soft, flexible feel with added density. They aren’t just rigid little sleeves. The idea is that they conform around the connection while helping protect it from weed, debris and general bottom clutter. On a clean gravel spot, that can mean a neater presentation. Over a soft or choddy bottom, it gives you another way to keep things controlled.
The shape is doing plenty of the work here. One end is small-bore and tapered, designed to grip most lines. The other is larger, blunt-ended and made to fit over most rig components. That makes the cover more versatile than a basic straight sleeve. You can use the end that suits the job rather than trying to force a fat component through a narrow opening and turning a quick rig change into a full-on faff.
That tapered profile should also help reduce snagging and weed build-up. Nothing is completely snag-proof, of course, especially when you’re fishing nasty Canadian pond-style weed or dragging a rig through soft debris. But a smoother, less abrupt shape gives weed fewer edges to catch on. It’s a small detail, though small details are often what stop a decent rig becoming a tangled mess.
The ribbed exterior is another clever bit. It gives putty more surface area to grip, so you can add a little extra weight if the rig needs pinning down. That’s useful for keeping the final section close to the lakebed, especially when you’re fishing a cautious presentation where you don’t want the rig waving about above the bottom.
Where these covers really earn their keep is on rigs with a crimped loop or an exposed connection that you don’t fancy leaving unprotected. They can tidy a chod-style arrangement, cover a knot on a heavier leader setup or help smooth out a component that might otherwise pick up weed. They won’t magically sort poor rig mechanics, but they can make a good rig more streamlined.
There are a couple of things to bear in mind. Ten covers isn’t a huge number if you’re forever tying fresh rigs, and the cover does add bulk around the connection. That won’t bother most carp setups, but it may be a bit much for ultra-fine work or tiny coarse-fishing rigs. Still, for anglers who like a clean, protected and bottom-hugging presentation, these are a cracking little addition to the tackle box.

Our take
Small covers, proper bank-side benefits
The Rock Bottom covers sit in that useful middle ground between rig protection and presentation. They tidy up exposed knots and crimps, add a little density and help reduce snagging points where weed can catch.
The main thing is matching the bore to the job. The small-bore tapered end grips most lines, while the larger blunt end is made to fit over most rig components. Get them seated properly and they should stay put rather than sliding about the rig.
A closer look
What you’re actually buying
This is a ten-pack of tungsten-impregnated TPE covers, each measuring 15mm by 5mm by 5mm and weighing 0.3g. They’re supplied on a wire applicator, which is handy when you’re threading a small cover over a knot or component without losing your rag.
The small-bore tapered end grips most lines, while the larger blunt end is designed to fit over most rig components. That gives you a bit of flexibility across crimped loops, knots and other connections. The outside is ribbed for better putty adhesion, and the tapered profile helps reduce weed and snagging points.
Worth knowing. These are covers, not a replacement for a sound knot, crimp or rig. Make sure the connection is properly formed first, then use the cover to protect and tidy it. Don’t rely on the sleeve to hide a dodgy job.
Who it suits
A tidy option for bottom-hugging rigs
They’ll suit carp anglers using crimps, looped connections or rigs where an exposed knot could collect weed. The added density is useful when you want the end tackle held close to the bottom, particularly on silt, light weed or choddy ground.
They’re also a decent choice if you like putting a bit of putty exactly where you need it. The ribs give the putty something to bite into, so you can fine-tune the rig rather than moulding a big blob around the leader.
For ultra-minimal presentations, tiny float rigs or anglers who never use crimps, they may feel unnecessary. The cover adds some bulk, and ten pieces won’t last forever if you’re constantly rebuilding rigs.
FAQs in full
Quick answers before you tie one on
Can they cover knots as well as crimps? Yes. They’re designed to cover and protect knots, crimped loops and other rig components. Pick the end that fits, then slide the cover into place with the applicator.
Will they stop every weed problem? No, mate. They should help reduce snagging and weed build-up thanks to the tapered shape, but heavy weed can still grab any rig. Think of them as a tidy-up and presentation aid, not magic armour.
Worth knowing. The tungsten content adds density, but the covers are still small. Use the ribbed exterior to add putty when you need more weight, especially if the rig needs to sit hard on the deck.

Yes. The ribbed exterior increases the surface area available for putty adhesion, making it easier to add a touch of extra weight when you want the rig held tight to the lakebed.
