Why buy this
Buy this when you want a metal trainer with room to grow
Acrylic is brilliant for first sight-based learning. A brushed aluminium repinnable lock is the next step: still visible, but more substantial in the hand and more flexible as a training platform.
Metal feedback
A solid body gives a firmer bench feel than lightweight clear trainers.
Rebuild the lesson
Use the included pins and tweezers to change the lock as your practice develops.
Cutaway diagnosis
See what is happening, correct the error, then repeat by feel.
Practice route
How to progress with it
Set an easy pinning first and learn the lock. Then add one variable at a time: another chamber, a harder pin, or a lighter tension target. That keeps the feedback useful instead of chaotic.
- Start simple before loading every chamber.
- Use the cutaway view to find oversetting and heavy tension.
- Keep pins organised in a tray while reconfiguring.
Helpful next step: Lokko Lock Pinning Tray.

Questions
Quick answers
Why choose aluminium?
It feels more substantial than acrylic while still giving the visual help of a cutaway trainer.
Is it beginner friendly?
Yes, if you start with a simple pinning and add difficulty slowly.
What makes it different from a fixed trainer?
You can repin it, so the same lock can teach more than one lesson.
What should I add?
A pinning tray keeps springs, pins, and experiments under control.
Give your practice bench a reconfigurable metal lock
The Aerospace trainer is built for pickers who want visibility, weight, and the freedom to change the challenge.

Airedale tough!
Color: Rubber Chew Toy, Size: Large
We have two young Airedale Terriers and I thought this would be a good inside toy for them to tug. And I was right! Very happily so. I have to admit I was surprised when I first saw it; it seemed so small. But the thing stretches and springs back to shape. We’ve had it about 2 weeks now and it is constantly played with. Absolutely the best toy! Very interactive either alone (it rolls) or with us or they play together. I am surprised how tough it is with all the constant rough play. Highly recommend!!!

Small, but twisty and fun looking. Seems relatively sturdy, though doesn't look indestructible at all.
Color: Rubber Chew Toy, Size: Large
SLIGHTLY disappointed because I thought this was bigger than it is. If you squish it all in close, it's maybe one and a half times the size of a tennis ball. (Of course, the size is probably listed; I think I just assumed, so my fault.) That being said, it's entertainingly twisty and squishy, though the rubber seems relatively sturdy. I'm not yet positive if it will hold up to the 8 month retriever/lab mix it's intended for; he tends to rip instantly through anything much less sturdy than kong natural rubber. But it seems like something that will amuse him, so we're going to give it a shot at Christmas.

Great product!
Color: Rubber Chew Toy, Size: Large
My dog is an aggressive chewer. I have bought this 3 times for her she loves to play tug and fetch with it. They last longer than most of the other toys I get her and it’s one of her favorites.

It’s okay I guess
Color: Rubber Chew Toy, Size: Large
Good price and decent toy, seems well made. My puppy is entirely uninterested and doesn’t play with it at all.

Very dangerous for chewers!!!
Color: Rubber Chew Toy, Size: Large
My dog was chewing/swallowing the hard rubber within seconds of having this "toy"!!! Not safe, sturdy, no play attraction; only desire was to consume!!!
