20mm Sheave Single Extreme High Load Block A2020XHL

XHL blocks have been designed to deal with extremely high static loads without compromising on low load dynamic performance. 

Ideal for use in kicker cascades or halyard turning points where static loads can be extremely high but low load fast rolling speeds are required.

XHL Bearings – Twin rows of stainless-steel ball bearings running on a stainless-steel axle with the addition of a protective plain bearing washer.

A key feature within the XHL bearing system is the precision plain bearing washer. When the XHL is exposed to extreme static loads (which would normally cause damage to the internal bearing system) it changes to a plain bearing block. This stops the ball bearings from getting damaged and thus no longer performing as designed. As soon as the static load is reduced the XHL returns to a high-performing dynamic block.

Body – The aluminium body features “ears” at the top of the block. These are to be used when attaching the block and stop the block from capsizing when under load.

Sheave – The stainless-steel sheave allows the block to be paired with both rope and wire.

This 20mm range which has been incredibly popular with the ILCA/Laser sailors for secondary line in the kicker.

Features

  • CNC machined aluminium side cheeks.
  • Precision turned stainless-steel sheave.
  • XHL Bearing Technology.

Room divider
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
I was looking for something to separate my two boys and give them both their own space. So far this room divider has worked well. It’s 6 feet tall and the fabric is dark and thick. You won’t see anything on the other side. Good quality and easy to assemble ✅

Too Cumbersome
Size: 6 Panel-119"W, Color: Black
Didn’t realize there were over 100 pieces to put this thing together. Had I been advised of that I would not have ordered this thing. Wayyyyy too much of a production to put it together. Nope. Returned.

Great Product, But Non-Existent Seller Support
Size: 6 Panel-119"W, Color: Black, Size: 6 Panel-119"W, Color: Black
The Good: Well Designed: Sturdy and aesthetically pleasing. Effective: Perfectly obstructs the afternoon sun glare from my monitor screens. Moderate Assembly: Straightforward and easy for the most part. The Bad: Defective Part: One crossbar end was missing threads, preventing the assembly of the sixth panel. Zero Communication: I emailed the seller as instructed and waited 8 days with no acknowledgment. Return Logistics: Amazon offered a return, but the box is heavy, and disassembly/repackaging would be a major task. Final Verdict I really like this product, but I’m deducting two stars for a total lack of customer service. I’ve decided to buy tools and fix it myself rather than deal with a heavy return. I hope the seller sees this and reaches out. The lesson learned is to check every part of a product before assembly.

Clean Look, Sturdy — can’t ask for more!
Size: 6 Panel-119"W, Color: Grey, Size: 6 Panel-119"W, Color: Grey
Really like how it folds so I can create kind of a doorway with two of these. Pretty easy to assemble and has an uncluttered clean look due to the smooth fabric and nice color. Oh and it’s sturdy enough for pets.
