Hi Lauren,
Thank you for your question. These are high quality industrial stair treads. The prices are for one stair tread, and the Yellow strip is not optional on this listing. However, here is a link to the same exact treads but without the Yellow strip, https://kofflersales.com/product/stair-treads-safety-rib-by-roppe?cid=65
Thank you,
