After much consideration there's really no safe way to ask this question. Background info: Attic access scuttle (hole) is at the opposite end of the house I'm working in. Back and forth across about 40' of ceiling joists. Had some cheap a** foam rubber knee pads (single strap), that kept inverting themselves, catching the ladder on the way up, or on a joist. What brand/kind of knee pads do you folks recommend? Thanks, pete
