Weight Bearing Belay?

Hi folks, since I'm new to the sport, I'd like to ask if any gear heads could help me get stronger.

I saw this video about this Redcord suspension device for training and rehab and was wondering what climbing gear I could use to reproduce the same results.

I like it because it is rated for 300lbs and is a simple system. Is this just using some inline belay device? Seems like I could make one with some strong non-elastic rope, a couple carbiners and a suitable locking device...?

Any recommendations for me? Thanks! Blush

Obviously, you will need 2 solid anchors in the ceiling. As for the adjustable cords/straps, just use some 6-7mm cord and a tent hitch.
No need for any expensive stuff to hold 300lbs... Tongue

Hi, thanks for the reply!

We have a solid pullup bar already mounted through reinforced trusses and built up infrastructure in the attic through the ceiling -- the pullup can hold four big guys no problem.

I liked the Redcord idea because it seemed all I had to do was throw the cord over the bar and back through the locking mech to get the easy-to-adjust height feature it provides, not to mention the loose end doesn't need to be tied down or held.

I'd rather not use knots because the load weight height down from the bar needs to be easily adjustable like the Redcord mechanism is.

Any other suggestions?

The taut-line hitch is easily adjustable.

Ok, so you're saying to throw the rope over the bar and then taut-line hitch it back on to itself somewhere or are you saying to use that at the top to tie the rope to the bar?

Where would the load bearing weight hang from?

Like this, where the knot position would determine the distance of the load from the bar?


Code
/bar\

\knot

load

^^^absolutely correct.
That is why the taught-line hitch is also called a tent-hitch. If you rotate your ascii-schematic 180, then you get the setup for holding a tent. The tent peg takes the place of the "bar" and the tent itself is the "load".

Thanks.

What sort of weight could like inline knot hold? For example, could it hold the weight of a person without slipping up the rope?

Unfortunately, I can't really give you a number on this. It will depend mostly on the diameter of the cord, the number of wraps in the knot and how slippery the cord is.

With the right combination of the factors listed above, definitely!
