High Patrick,
Thank you for your question. Both of these products you sent us links to A638. A638 is for abate feet applications, such as showers and tub areas. Maybe you meant A636, which is to be used for areas were there is shoe traffic, such as ramps steps and warehouse floors. Here is the link for A636, http://kofflersales.com/non-slip-tape-anti-skid-adhesive.asp.
