Lone Peak Labs | New Grab Handle winch pull test

Kyle and Tyler hooked our new grab handle prototype to a winch and a truck to see what breaks first. Watch the video above, then tell us what we should try to break next.

How should we test the Grab Handles next?

  • Same test with a solid anchor and more force
  • Shock test by starting with slack in the line
  • Run over to the guys at HowNot2 over in North Bend! (Climbing gear test)

We redesigned the grab handles and wanted to see if we could break them

Grab handles get used and abused. So if we made a new version, we didn't want to just tell you it was tough. We wanted to try to break it on camera.

In the video, Kyle and Tyler from take the new handle out to the trucks. Tyler was nervous about hurting his truck, so the plan changed: his tire went on the truck, and Kyle pulled with his winch. The full video is the Lone Peak Labs Short on YouTube if the player doesn't load.

What changed in the new grab handle prototype

Material. The new handle is injection molded from a glass-filled nylon made by DuPont. As Kyle puts it in the video, it's the same kind of stuff they make Glock frames out of. We wanted something stiff and tough without going to metal.

Mounting. For the test, we bolted the handle to a scrap section of one of our camper uprights, the same kind of part it mounts to. Two small blocks sit inside to keep the load as even as possible across the mount.

How the winch pull test went

Neither of us knew what to expect. Tyler said it best before the pull: "I honestly don't have a clue on how much this will be able to handle, but we're going to find out soon." We put a scale inline to read the force.

Here's what happened:

  • The scale peaked somewhere around 700 lb ("700 change," per Tyler).
  • The handle didn't break. Neither did the bolts.
  • Instead, the load started dragging Tyler's truck, tire rotating and all.
  • Kyle expected the bolts to pull through the socket, since the wall there is fairly thin. They didn't.

Short version: we ran out of anchor before we ran out of handle. Tyler also wouldn't hook it to his actual hitch, because he didn't want it to fling back and hit his "beautiful white taco." Fair.

Why this is turning into a two-part test

We haven't been able to destroy the new grab handles yet, so this is now a series. Next time we're finding a sturdier mount and going again. Take one is in the video; take two is coming.

How you can help shape the next test

  1. Tell us what to try next. Reply below with the test you want to see in part two. 
  2. Tell us how you use grab handles. Climbing in, tie-downs, something else? Real use cases help us design the right test.

Maybe use the same scrap piece but attach it to a winch anchor around a huge rock, then use the winch on the handle as before?

I’m perfectly happy with the current grab handles, but I’m curious what made you decide to redesign them. Was it to reduce weight, bring production in-house in the US, or because of rising aluminum costs? The video definitely proves how strong the new ones are, but I’d love to know what improvements they offer over the current version and whether there were any issues with the original design.

@Toku Akashi Hey Toku, the main goal was to reduce cost. We'll be including them with the new Straight Pop camper to be used for self-installing.

@Kyle Hart That makes sense! Great idea! If they’re compatible with the current campers and sold separately, I’d definitely buy a couple! I really like the current ones too.

You guys should connect with 'How not 2' he's always breaking climbing gear and stuff like this. Also I'm sure you'll get a different result if the loading force will be perpendicular to the handle base. Which would be lifting the camper with a telehandler and handles installed on the top horizontal rail. https://www.youtube.com/HowNOT2
