MATTING |
1/2” Tuff Spun mat |
3/8” Tuff Spun mat. 1/2” is available but adds 3 pounds to box weight |
|
MECHANISM |
Plunger style firing mechanism |
Lever style firing mechanism. The lever style is self-cleaning. When cocked, it will always fire. It is also dual-action in that it throws small balls as they rest against the plunger and strikes larger balls similar to the pin style. No need for large and small ball firing mechanism. |
|
FASTENERS |
Stainless Steel |
Aluminum and Zinc plated steel. There are 113 aluminum rivets holding the box together, and each is rated for 1300lbs in shear (most of the forces on the rivets are in shear) and 830lbs in tension. The hardware on the hinges is 3/8" zinc-plated steel, which was chosen because it is "harder" than stainless steel and resists stripping and shearing. |
|
SPRING TENSION |
N/A |
Combined spring tension is just over 70 pounds. A fast, average-sized Border Collie generates about 140 lbs of horizontal force which translates to about 100 lbs of downward force on the spring. The Border Collie will fully compress, but slower or lighter dogs also benefit from the spring action as they actually can compress the springs slightly. |
|
FRAME |
Rigid frame Plastic sides and base
|
Spring Back Frame - Powder-coated Marine Grade Corrosion resistant Aluminum. Reduces shock on joints – please see video. |
|
WEIGHT |
57 pounds |
27 pounds. Easier to transport and easier on the boxloader. |

Spring Back Hybred |
Miller Elite |
|
APPROACH |
49 degree angle – 45 optional |
40 degree angle. Optimized for maximum landing pad and generating force downward so box does not move when the dogs hit the box except for the spring compression. The higher the angle the more force generated back and less into the springs.

MECHANISM |
Pin-style firing mechanisms |
Lever style firing mechanism. The lever style is self-cleaning. When cocked, it will fire. It is also dual-action in that it throws small balls as they rest against the plunger and strikes larger balls similar to the pin style. No need for large and small ball firing mechanism. |
|
FINISH |
Anodized aluminum is the only coloring option, at an additional cost. Anodizing can easily be removed with cleaners like "Greased Lightning", warning label on bottle says not to use with anodized aluminum. |
Powder coated finish goes on dry and is baked into the aluminum. Most household cleaners will not damage finish. Use with the same care you would with your car's finish and you will have years of like-new look. Powder coat is very difficult to remove, except by sandblasting. |
|
SPRING TENSION |
Spring tension is drastically higher than the Elite, although exact resistance is not listed. |
Combined spring tension is just over 70 pounds. A fast, average-sized Border Collie generates about 140 lbs of horizontal force which translates to about 100 lbs of downward force on the spring. The Border Collie will fully compress, but slower or lighter dogs also benefit from the spring action as they actually can compress the springs slightly. |
|
FRAME |
Open frame with plungers (firing mechanisms) exposed. |
Closed frame construction that is light-weight and strong. Cannot accidentally misfire or injure the boxloader. |
|
BOXLOADER COMFORT |
No place for boxloader to brace legs.
|
Back is enclosed and padded, giving the boxloader a place to brace legs. |
