Karver KJ10 High Load Jammer Rope Ø 5-10mmThe KJ10 is the original aluminum version of our 3 jaw heavy duty jammer. The secret of KJ jammers lies in 2 simple technical elements : a conical shape where the more you pull the more it gets stuck and the use of 3 jaws to distribute the load over 360 so as to never flatten or damage the ropes. The jammer is no exception to the chore of cleaning but this has been thought about: The ascender is in 2 parts which makes it possible to extract the jammer

The KJ10 is the original aluminum version of our 3-jaw heavy-duty jammer. The secret of KJ jammers lies in 2 simple technical elements : a conical shape where the more you pull the more it gets stuck and the use of 3 jaws to distribute the load over 360 ° so as to never flatten or damage the ropes. 

The jammer is no exception to the chore of cleaning but this has been thought about: The ascender is in 2 parts which makes it possible to extract the jammer very quickly without having to disassemble its glued – screwed support. The result : an innovative and efficient jammer that does not let go and that does not damage the strings.

Rope Ø 6 -11mm

– Innovation : 3 jaws surround the rope (instead of 2 on all other jammers on the market). The load is distributed on the rope and the sheath wears less.
– Innovation : The conical shape accentuates the hold of the rope. The more you pull, the more resistance there is.
– Design : The cone containing the locking mechanism can be installed without its foot in a reinforced “sock” installed in any location : deck, boom, mast, bowsprit,…
– Convenient : The KJ can be ordered with or without its stand
– Practical : The opening and closing (in the axis of the rope) can be controlled remotely by installing extensions. The jammer is installed as close as possible and limits the undesirable effects of the elasticity of the rope. It is very often found as a jammer on headsail tack.
– Performance : The rope does not slip. There is very little recoil when blocking.
– Convenient : the jammer can be removed from the foot without tools. Maintenance and cleaning are easy. If necessary, the cone can be replaced very quickly.
– Performance : Extremely compact and light.
– Design : The jammer can be installed in very small and even hidden locations.
– Performance : In the open position, the jaws open wide and offer very little resistance to the rope 
– Performance : The reduced wear of the sheath greatly limits string replacements. Investment in technical ropes is relevant
– Ergonomics : No constraint on the operations height (unlike a jammer that opens from the top : Each KJ can accommodate a wide range of diameters without affecting performance
– The KJ is also available without its foot (KJ CONE) in order to be installed in a laminate slipper

They hang easy!
Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 23-inch, Color: C. Rustic Brown Board & Black Brackets, Number Of Shelves: 4, Size: 23-inch
I got my shelves well packaged. No defects. I did find it odd that the photos show a third way of hanging them where the brackets are hidden, but it's the only two top shown in the product photo of the hanging options that are shown on the instructions. It's easy enough anyway to hang without any instructions and I chose the second one shown anyway. They're good quality and look nice on my wall. Color is accurate and holds all my stuff the way I'd hoped/imagined. I wanted shelves that didn't stick out too far from the wall and they're a great fit. Super sturdy!

Great product!
Color: G. Black Board & Gold Brackets, Number Of Shelves: 3, Size: 16-inch Mixed, Color: G. Black Board & Gold Brackets, Number Of Shelves: 3, Size: 16-inch Mixed
The feeling of the shelf itself is a little off but it was super easy to put together and looks great! It comes with a mounting guide but I didn’t need it. I didn’t use to wall anchors and just screwed them into the wall and they haven’t been a problem at all!

Avoid the GOLD brackets. The finish is NOT accurate.
Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch, Color: G. Black Board & Gold Brackets, Number Of Shelves: 4, Size: 16-inch
I bought the BLACK/GOLD shelves because the ones in the photo seemed to match the drawer pull knobs I bought (shown in photo below). The product arrived neatly packed in a 17x6x4in. box. I can only assume the shelves themselves are great, but I only made it as far as inspecting the metal brackets sitting at the top, they feel heavy duty, which is great, but the product's photo posted in Amazon shows a nice gold finish, and these brackets have a dark mustard paint finish (with a couple blueish speckles sprinkled into it), there's nothing gold/metallic about it. The paint color reminded me of long-gone diaper-changing days. These are getting returned asap.

Simple, easy, and strong
Size: 16 Inch, Color: White
Kind of on the smaller side but for the price it’s just fine. Easy to install with just a screw driver if you can miss a stud, else you’ll need a drill. Strong enough to hold what a normal person would put on a shelf that size. No worries and it looks great
