Screeching Companion Way Hatch?  Many years back Graham Mackay posted a solution to a screeching companionway hatch sliding against the cabin top.  I followed his instructions to the letter and it solved my problem.
New problem is I needed to buy a huge sheet of plastic 48" x 92" to get (2) 1"x 72" x 1/16.  So needless to say I have the ability to make a lot of strips.  If you have a screeching hatch  $15.00 paid to paypal will deliver a set of pre cut strips to your door.  These really work they install in minutes with no removal or alteration to the hatch assembly.  You won't find a cheaper way to obtain this material unless you get lucky in the left over material pile, LOL  Please include your mailing address and email address.  www.paypal.me/markholzmann/15
