Well, Roy Cook is right again.
I revued the picture again, and I’ll be darn the angle of the picture threw me off.
Roy must have been in his recliner at the time he was looking at the Pic. ha. ha.
This does seem like a tie off, and the sling attatchment must have been taken out through the ridge vent slot in the peak. In no way is this an approved tie off, if that is in fact what it was. Looking more closely, I saw the two deck screws penatrating the truss. This those not meet the 5000# loading attachment requirement. Eyebolts are most commenly used because they meet the OSHA requirement, and either left or removed when the ridge cap is installed.
Raymond, you are correct in saying that nylons slings are commonly used for erecting truss packages. That is what I use. Commonly eight trusses at a time and choked around a truss member and the permanent lateral bracing which helps pick up the other trusses.
A module of eight allows you to install lateral bracing in 16’ lengths and scabbed later with a two length truss splice.
All goes to show you that you can stare at a small picture all day and it does not tell the whole picture.
Thanks Roy for that good pick up on that window. You can send your recliner back now. ha. ha.
