6061 aluminum alloy : nylon sling : synthetic rubber

SLING
Sterling Ropes 5mm accessory cord 4” short sling : 10” long sling
we recommend the short sling version for a smaller and lighter block, also makes ground pulls easier
carabiners or additional slings can be attached for a longer reach

OPEN DESIGN
we spent a lot of time designing this block to be lightweight and strong
not having a full pocket allows the block to have the same great functionality without the added bulk

TEXTURE
unique sandblasted aluminum provides a comfortable and grippy feel
stronger and smaller than wood and more skin friendly than plastic

DUAL FINISH
we go to great lengths to ensure the center spine of the block stays mirror smooth
this is keeps your fingernails from getting scratched up or feeling like nails on a chalkboard

ROUNDED EDGES
cnc milling usually uses 45 degree chamfers to dull sharp corners because its fast
we took the extra time to round edges for the smoothest finger feel possible

VISUALLY BEAUTIFUL
tenoclock is a design studio
we strive to make products that are not only functional but look amazing too

each 20:10 block comes with the machined aluminum block and a pre-tied sling, rope ends are dipped in liquid rubber to prevent fraying and add a pop of color

each block also comes with a tenoclock sticker
