Straight Drop Boot
GSI 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 Degree Drop Boot
A 30 degree 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" & "twin through" models which can be used in tandem where two tanks are used in line.

Parabolic Boots
GSI's 16" (406mm) parabolic boot (available in straight drop or 30¼ models) is made in our 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.

Single Unloader with optional swing away bottom for 100% clean out.

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

GSI's Clear Boot
GSI's clear boot allows producers to verify at a glance that feed is present in the bin. This boot is injected molded from a specially formulated, ultraviolet stabilized, clear polycarbonate blend and features a heavier wall to prevent cracking.

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