Tethrd One Climbing Sticks

[Plebe]

I too have the one sticks and experienced a glue failure on one of my three steps. I emailed Tether and received the following:

The ONE Stick steps are actually held on by a roll pin. The glue on the step is to keep it more secure. If the glue bond does pop and fail there is no safety concern since the roll pin is what is really holding the step on. There is a 1 year manufacturer warranty on any of our products. So if something does break outside of a 30 period then it will still be covered by the manufacturer warranty. The 30 day period is if customers want to return for a refund because they don't like it or want to exchange the item.

I then asked what that little tiny roll pin that was holding my life was rated for and was told 300 pounds WITHOUT the glue. Overall I like the sticks and plan to keep for now. Even tho the glue failed the movement in the step is barely noticeable. Love how light they are.

Thanks for sharing their response. It contradicts some earlier info, so I am quite surprised.

I agree sticks that are 2/3 weight of most competing options is something to love.

There's something about the grade 8 bolt through my beasts that makes me feel warm and fuzzy inside

what specifically about it makes you feel warm and fuzzy?

The safety aspect. Never worrying about glue popping

Wow... so now they are completely back tracking. The roll pin was supposedly just use to keep the step in alignment when glueing...oh boy...

Say whatever makes sense to get through the next 5 minutes. I wonder if the patent for their "weld process" will be granted?

I agree. Why the roll pin I have no idea. Definitely a design flaw but with several months to hunting season I’ll try em and keep an eye on em. If it gets worse back to Tethrd they will go.

After the return period you'd likely only be able to return for replacement, not refund.

Reading into the response.... it doesn’t seem a glue popping would warrant a replacement either as long as the roll pin is still intact.

If that's the case I'll never buy another tethrd product

I feel like this would be a deal breaker for me as well, despite really enjoying the product. The glue popping isn't the issue for me, so much as the way they are responding to it. I couldn't imagine the strain that must be on those guys at the moment, all things considered. Hard to say what way I would respond because I'm sure it will have major financial implications.

But what specifically about a grade 8 - 1/4" bolt makes you feel warm and fuzzy?

Is it just because aren't familiar with the glue/roll pin application? I'm trying to understand very specifically what makes you comfortable.

We have problems outta the box before the season even started with glue/roll pin. For sure we won't know the extent until people use them during the hunting season. I've never heard of a 1/4 bolt giving way on a beast stick. That makes me comfortable. Don't overthink it

What specifically are you insinuating by questioning the integrity of a grade 8 bolt? I'm curious why you are so adamant about questioning a grade 8 bolt?

Tethrd just seems like a joke to me.. keeps getting worse in my eyes. The email about the glue and roll pin sounds like a cop out instead of acknowledging that maybe they should’ve thought it out more. Idk much about titanium, is it hard enough to not wear out over time? Or do you gents think that roll pin is going to round the tube out over time?

Thought the steps were chemically bonded with glue and the roll pins were to help hold the steps in place? Is Tethrd doubling back on their claims or are these rumors?

I'm questioning being comfortable with a grade 8 bolt because of warm and fuzzy feelings. What I'm getting at with my desire to see test results, and failure modes, and calling into question being comfortable with a bolt instead, is that I worry about folks being comfortable with things they shouldn't be.

We can all do what we want. But it seems like we make certain assumptions about one way of doing things, and make different assumptions about another way of doing things. And in reality, we know very little about both.

"Standard" stick design (1/8" wall 6061 tubing and 1/4" grade 8 hardware) were around before hunting forums were as popular as they are. Failures wouldn't have been as "viral" as they are now. Does anyone here know if lone wolf or others experienced similar issues in early designs?

I don't. I also know it's pretty easy to run both virtual and real failure analysis on that old school design. It's well studied often used materials.

But, does anyone here know what type of testing/failure analysis any other stick manufacturer has done? Does anyone know what the results are?

This is a pretty unique method to build a climbing stick. I have no doubt some sort of failure analysis was done. I'd be curious about the results. People may be rightfully freaking out about glue letting loose. Or roll pins working their way loose or shearing. Or, Tethrd might have a 3:1 safety factor that holds through a million duty cycles.

Would anyone's opinion of how safe they feel on the steps change if they knew that Tethrd tested sticks in that manner and they passed? Mine would change.

But I don't feel "safe" on a standard stick design for two reasons - I've never seen test results; and the risk baked into climbing a tree at all, far exceed the risk of any of my commercially available options "failing" during said climb.

Just trying to get folks to think, that's all.

Tensile strength of 1/4-20 grade 8 bolt is around 4750 pounds. Proof load is 3800 pounds. The fact that’s there’s NO MOVING PARTS on Beast sticks mean the bolt will not wiggle and bore out the hole.

Now the roll pins on these One Sticks wiggle and are probably not Grade 8 hardware...

I’ll trust my life with the product that has no moving parts and quality hardware.

Not arguing your point on margins of safety in the least. However, the one failure mode that a headless pinned assembly has that a bolted joint does not is an inadvertent displacement of the pin. For a bolt to displace either the nut needs to fall off or the head needs to shear off. A pin pressed into a through hole has no secondary support if it loses its press fit, or glued secondary retention.

I fully believe the pinned joint is strong enough on itself to support the required loads, as long as the pin stays in place. It's when it shifts one way or the other that the strength of the joint comes into question.

Tethrd tested the sticks without the glue in the TMA laboratory and they passed.

They tested it in the laboratory...yea thats nothing like the abuse people will give them in the real world. Also im hearing they changed the plate that they used to do the pull test to accommodate the the step design

A bolt doesn’t just come out on you like a pin can. Enough said

Tensile strength of 1/4-20 grade 8 bolt is around 4750 pounds. Proof load is 3800 pounds.

The load is applied much differently with traditional sticks. There's much more of a moment arm creating a pulling and bending load. The roll pin is in much more of a shear configuration. I suspect that the pin itself is highly unlikely to break.

I fully believe the pinned joint is strong enough on itself to support the required loads, as long as the pin stays in place. It's when it shifts one way or the other that the strength of the joint comes into question.

The pin coming out (it's unclear if that's a legitimate concern), or the pin damaging the tube, would be more likely. Or something causing the tubing to buckle.

The design itself seems relatively sound, but the inconsistent and misleading communication regarding the purpose of the pin and the reliability of the adhesive bonding are kinda showstoppers.

A bolt doesn’t just come out on you like a pin can. Enough said

I've certainly had bolts come loose over time.
