Dual gate...will these work for arbos?

[Tom Dunlap]

OK...if these were available in auto-locking gates how would we use them for treework?

A clear view

Of course its well past midday here sooo....it don't count

 

[banjo]

Nice try!!!!!

 

[tomthetreeman]

Ha! What day is it?

HAHAHA this happened last year. I think they would work without too much effort.

Let's take an April Fools gag and turn it into something useful?

Envision an ancient ship's anchor with a stout midsection.
Now make a biner using that same design, but with a triple locking gate on each side. This type of biner would make an ideal arborist's biner for use as a lifeline redirect on a DRT. No rope to rope friction between the two lines traveling in opposite directions!

Indeed rollers could be added to the anchor biner's bottom flares to reduce rope to anchor friction even more more.

Thus an fool's gag can be mutated into an extremely useful arborist's tool clipped to every climber's saddle!

Take that Tom!

J...I came across this biner probably 5-6 years ago...it's a running gag.

Do you really think that I haven't thought about the use of a double gate 'anchor' biner?

When I talked with Denny Moorehouse/ISC he agreed he could make it...but...to what end? Is there a market? He, and I, didn't think so.

YOu can find the same solution using a double sheave pulley and an available biner.

Got any pics or links to it Tom?

Are climbers who use redirects alot like me an unviable market or something?

Took me about three seconds:

I have the redi pulley...the top configuration keeps the ropes tight inthe sheaves so that they don't jump and cross.

Do you need a link to a biner pic?

To me...the viable market is SRT. The whole issue of friction in redis doesn't exist!

Thanks Tom, but I still think a single double gated biner would be lighter, quicker and less cumbersome in the tree.
