Aahhh, let alone the location of any pre / post tensioned cables. Think your yak / car can support whatever is on the floor (s) above you??

I wouldn't think that any strand would be _THAT_ close to the bottom surface, but it would serve as a reminder to not drill too deep!

Hello List, I've been reading these posts about putting concrete anchors in the roof of a parking garage and I feel like some words of caution are in order. Actually, chicken that I am, I was hoping someone else would have said this first, but... I'm thinking here that we are talking about an installation by amateurs, not professional carpenters or concrete people. I know that you can drill into concrete and, if you don't hold the drilling device steady, you can enlarge the hole and perhaps make it not round. This is not too hard to imagine when you are drilling overhead as in a garage roof. I'm thinking also that the holding strength of the anchors is directly dependent on the diameter and regularity of the hole. So what this is leading up to is that you may feel you have a solid installation in the concrete but, in fact, you do not. You need to ask yourself: 1. If I hang my boat there and the installation fails, will I be hurt, will others be hurt, will my boat and/or car be hurt? 2. What will happen if, while I'm away paddling and someone else wants to use these eyes say to hoist the engine out of car? Will I be accountable for the damage when the eyes pull out? All in all, my opinion is to stay away from this type of installation all together. I know this doesn't help with the boat storage issue but it may save some grief in the long run.

Here, however, you are talking about no more than about 100 lbs divided into two anchors. Not an impossible weight. Also, if out of round or enlarged, installing lag shields then the bolts should take care of any problems. *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
