aluminium rope window for synthetic ropes
made
cnc-milled to industry standards
The thicker high-strength aluminium window leads to a larger outer radius against which the plastic rope can glide.
This results in a lower load on the rope fibers at high angles and increases the service life of your synthetic rope.
Which is the best surface finish for aluminium rope windows? It is undoubtedly a hartanodisation. Non-cosmetic anodized surfaces, non-powder coated, and not raw or polished aluminum Why?
Because a normal coating cannot withstand the abrasion damage caused by a dirty/seer-like plastic rope that rubs over it.
Especially for extreme side pulls, where the stress on the cable fibers is extremely high.
A hard-loxed surface leaves a .002' thick layer in the top 5 of the hardest materials.
Another valuable material property of hard anodisia layers are the low coefficients of friction. Low friction = less rope heat.
Only one drawback? Hard-loxing is not offered in typical bright and unusual anodised colours.
