The Best Boot Possible - The Parabolic Boot

The 16” (406 mm) parabolic boot (available in straight drop or 30” models) is made in our manufacturer's own facility from the very latest in ultra high impact polypropylene for greater flexibility, dependability and durability.

Most of our competitors still use the older ABS plastic, which is stiff, brittle and prone to fracture, cracking and tear-out, especially where it's attached to steel. It is impossible for ABS to be UV stabilized, thus creating a built in deterioration factor over time.

In addition, AP's polypropylene resin blend contains special chemical ultraviolet light inhibitors and impact modifiers to further enhance durability and resilience.

The Clear Boot

The clear boot allows producers to verify at a glance while driving by that feed is present in the bin. The heavy walled boot is injected molded from a specially formulated ultraviolet stabilized clear polycarbonate blend to provide years of trouble free service. It features a heavier wall to prevent cracking.

Heavy Duty Metal Boot

Multiple outlet requirements can be easily handled by our 22” (559 mm) all metal boot. This boot, which can be fitted to any AP feed bin, will allow installation of up to four feed lines in several directions at once.

Straight Drop Boot

Our supplier manufactures its drop boots from a polypropylene resin blend containing special chemical ultraviolet light inhibitors and impact modifiers to further enhance durability and resilience.

30-1/4 Drop Boot

A 30º drop boot is also available for rigid augering or similar inclined feed delivery systems.

Double - Through Unloader

Most unloaders are available in single or double outlet models, as well as “through” and “twin through” models, which can be used in tandem where two tanks, are used in line.

Feed Tank Unloaders

Designed to fit below the 16” (406 mm) plastic and 22” (559 mm) metal boots, these standard unloaders are available for 2.2” (55 mm), 3” (75 mm), 3.5” (90 mm) and 5” (125 mm) Flex-Flo™ or 4” and 6” rigid auger systems.

All unloaders have a slide-gate above the auger to meter feed or serve as a complete shutoff…and a convenient, inspection/clean out plate on the side, which is easily removed with two wing nuts.
