This I saw at the TB: http://www.youtube.com/watch?v=xSA9FBigH...Xq_9YjYzgxqYeAE, I'll take five of those!

Thoughts??

BMS Belay Spool $110.

HOw much can it actually lower with those wraps without hockling the F*&^ out of it?

How strong is that hook without the gate shut? I'd have to tape the gate shut. It would possbly open remotely via brush or a protrusion of wood.

Looks great for lineman.

I like the concept of the ox block- but yeah- those twists make it a no go for me.

Seems a rap rack could be incorporated to have the same function but twist free

Waiting for a 540 Rescue belay pulley I snagged on eBay for $75.00
Think it functions similar to a belay spool, but not as heavy duty.

"The well-engineered Traverse 540° is a patented, self-locking, easy-to-rig device that meets demanding drop-test criteria: able to hold falling loads quickly while limiting the peak force. The symmetrical design reduces the risk of improper rigging. A built-in release lever discharges the tension on the belay rope, eliminating the need for a release hitch."

 

[Pelorus]

"the 540° is rigged by opening the front plate, wrapping the rope one and a half turns around the spool, and closing the front plate..
When a heavy load is encountered in use, the spool will rotate to one side and squeeze the trailing end of the rope between the spool and the wing bars. This provides a dramatic increase in friction...the rope only makes a 540° pass around the spool as opposed to 900° on other devices such as the Bassett Metal Studios Belay Spool or the Single Rope Technique RBM Belay Spool, the additional friction generated this way is easily appreciated."

 

[SouthSoundTree]

Sounds like it pinches the rope? What is the release mechanism?

Let us know how it works.

I'll still recommend the BMS BS, at least until hearing your review.

 

[Pelorus]

I dunno how it works or how well it works - it won't even arrive for at least a week or two.
I ordered a BMS spool a few weeks ago and it will be neat comparing the two devices.
A new 540 thing is very spendy, compared to a BMS spool, but that is probably cause it's target market is FDs and search & rescue outfits.

What would be nice is if this:

would fit into one of the sheaves of the Rock Exotica Omni Swivel Double Pulley:

and you could get double duty out of it.

Cool design, but would probably turn your line into a corkscrew with knots after running a few yards weighted.

When I descend from a removal on the pull line -using a Munter hitch, the rope gets all kinked up. I imagine the same would happen with the OxBlock.
