T2™ blocks come in single and double configurations and can be tied, spliced, or lashed to almost anything.

T2 doubles feature composite line guides that are integrated into the block head. They prevent the block from capsizing by pushing the lashing line to the outer edges of the side plates. The 29, 40, and 57 mm blocks feature composite sheaves that spin freely on Delrin® ball bearings with curved bearing races. They have no metal shackles or rivets, making them the lightest soft-attach blocks Harken has ever designed.

All T2 blocks route the attachment line through the block head and sheave, decreasing the loads on the side plates and acting as a safety backup for the system. Use for traveller controls, main sheets and kickers, cascades, bridles, and other systems where small lightweight blocks are called for.

A length of Spectra® line is included.

The block attachment instructions can be found HERE

Very Firm Latex Medium, Appears Well-made
Size: Standard (Medium)
I love latex pillows, used them for decades. Then I got led astray! My neck reminded me I need firm, but soft and bouncy. This pillow is surprisingly firm for a medium. So think twice before ordering firm.

Comfortable but smaller than a standard pillow.
Size: Standard (Medium)
The pillow is bit smaller than standard length wise. It takes a while for the smell to go away. Very comfortable pillow.

Remarkable and impressive pillow
Size: Standard (Medium)
The pillow came quickly and was what was expected. After 6 months of chronic neck pain, one night on this pillow has made a world of difference. Please buy one of these if you are on the fence. They are wonderful. Highly recommend.

Not any more breathable than other pillows
Size: Standard (Medium)
I got this in hopes that it would be cooler than other pillows but it seems to hold the same amount of heat. Additionally, as a side-sleeper, it is too thick for me. It is however pretty comfy and seems to be made out of quality material. As other reviews stated, it was smelly at first but that went away within a week.
