Grady Smith on this product:
We take our 10' Single Safety Rails and weld two ribs near each end forming a one-piece integral unit. This completely changes the characteristics of the scaffolding safety rail package giving a feeling of solidness, rigidity and a secure feeling of safety and is quite comforting to me at height. These are for use with the Deluxe Safety End Panels only. We produce Deluxe Safety End Panels for our 5' widths and our narrow baker's frame which has a width of 28". They will not work with our safety poles. I recommend replacement of the budget rail systems at 20' and for those that want to feel really comfortable as low as 10' as well.
