Looking to upgrade my guide rail to the new nylon ripping edge. My Festool rail guide has the old foam edge and its difficult to accurately line the guide up to a pencil mark. The foam edge is not a clean edge after multiple cuts.

Festool calls this item a splinterguard. Link below to the clear splinterguards, currently available in 55" or 197" lengths.https://www.festoolproducts.com/catalogsearch/result/index/?q=clear+splinterguard&tn_product_type=Clear+Splinterguard
