The Fly Control for Cattle Mineral Add-Pack that Makes Keeping Flies Away Easy
- JustiFLY® Feedthrough is more effective than typical cattle fly control pour-ons for breaking the lifecycles of all four common types of cattle flies.
- This fly control mineral add-pack costs less than 6 cents per head per day.
- JustiFLY® is approved to control flies for both lactating and non-lactating cattle, as well as for use in both pasture and feedlot cattle.
JustiFLY® Feedthrough Benefits
- This fly control for cattle mineral add-pack effectively prevents the development of horn flies, face flies, house flies and stable flies in manure.
- JustiFLY® can also be used to control existing adult flies around manure.
- JustiFLY® Feedthrough can be used throughout the fly season in both non-lactating and lactating dairy cattle.
- JustiFLY® can reduce animal-handling stress.
- The fly control add-pack does not affect dung beetles.
- The fly control mineral easily passes through a cow’s system leaving no residue, requiring no withdrawal period and causing no resistance issues.
- JustiFLY® is more effective and easier to use than dust bags, ear tags, sprays, and cattle fly control pour-ons.
How to Use JustiFLY® Feedthrough
- Mix one add-pack with one 50-lb bag of free-choice mineral and feed your cattle with the mix.
- Cattle ingest the IGR larvicide as they feed on the treated mineral. It passes through the animal and starts to work on flies once it is deposited in the cattle manure.
- On average, each 360 gm. (12.7 oz.) add-pack treats 2 animals for 6 months (3 add- packs = 6 animals for 6 months)

Monster cable
Size: 4/0AWG, Color: 3ft Black + 3ft Red
Well I now know what 4/0 or 0000 cable is. Huge but very easy to handle or bend to shape.

Received the package in good condition. This wire is a decent quality. I made a set of jumper cables with it and they work excellent.

bought twice to make custom UPS setup battery leads, not disappointed
Color: Black, Size: 25-Feet
bought this item(25ft 2awg) twice, the first time I did was to create some quick connect cables between my batteries and my distribution block to my 4kw invertor(24v 165a peak calculated load)
I may have oversized due to knowing that the bigger you go the less you stress components and loose power to voltage drop
these cables are a nice high-grade rubber jacket and the 30awg strands are ideal for maximum flexibility while remaining fairly easy to terminate
this cable also includes a backer paper wrap that allows for easy stripping(of the rubber) without too much strand loss damage(from cutting too close to the core)
overall, would buy again, like I did, if I need larger runs(say for feeding an RV solar AC distribution panel) I would buy this brand again, in the 100ft range or so
THHN is not ideal for flex connections(strands are way too stiff) but a couple runs of welding cable like this inside something like "smurf tube" would be a perfect high-power temporary connection system, or just a way to isolate a large battery stack used for a solar setup
in fact I may do that someday, set up a pallet of LiFePO4 batteries with a large quick connect, and just recharge the massive array(s) at a secondary location where solar is more ideal(or other renewables)
