It is known now that diamond jacker plates, etc. eventually get slippery and form a safety risk, rather then preventing one. Now there are a lot of good products on the market, but the one that (at least to me) is really outstanding is Vigil Anti Slip. Their product is really fantastic when it comes to anti slip, but it is also really long lasting.
After we installed on the Markab on all stairs and ladders, we had zero slips and falls recorded. The product is still as new after 1,5 years heavy use. It is a big difference with the products from Safemate, No Skidding, 3M, which appeared to be all only short term solutions.
