The HD-STAX is a patented stackable elevator bucket designed for long life, more capacity, and economical shipping. Designed to stack (nest) together, the HD-STAX gives you almost 3 times more buckets per skid and container. The HD-STAX buckets slide together to provide up to 60% space reduction for storage and shipping resulting in lower costs.

The HD-STAX also features a thicker, heavier wear lip molded across the front and sides of the bucket, for a tougher, stronger and longer lasting design. The wear lip is almost 2” tall, and is thicker in the corners to give you sustainable life when used in tough agricultural applications.

HD-Stax Low Profile Option

A reduced height for closer vertical spacing allows more buckets per foot of elevator belt. When upgrading to HD-Stax Low Profile buckets, horsepower requirements must be evaluated due to increased capacity.

Other Considerations

DRILLING: Elevator buckets are manufactured without a drill pattern. Special drilling or punching can be accommodated upon customer request.

VENTING: Available as needed. See venting options in our catalog.

DIGGER BUCKETS: Use slightly larger metal digger elevator buckets to help loosen material in the elevator boot section that has set up or hardened, thereby reducing abrasion on the plastic buckets. Call for details on Metal Digger elevator bucket options.

SPACING: See elevator bucket spacing details in the size chart (depending on materials and speeds, smaller and larger spacing may be used).

INSTALLATION: Use a #1 standard elevator bolt or Sabre-Tooth elevator bolt for installation. Designed to be used with fender or flat and lock washers and hex or locking nuts. If buckets are being installed on chain, use hex head bolts, nuts and washers.

FDA: Both the urethane and polyethylene are designed to FDA specifications for direct contact with food products.

Venting an elevator bucket aids in bucket fill and discharge with light, fluffy materials. Lightweight, fluffy materials, those that are extremely dense or flow poorly can be difficult to handle in bucket elevators at high speeds. Because these materials tend to trap air when being handled by an elevator bucket, venting provides air relief to assist in their filling and discharge. Commodities for venting include flours, meals, feed mash, DDG’s  or screenings. As these materials enter the bucket, air is released through a series of vent holes in the bottom of the bucket allowing for a more complete fill. These vent holes also allow air to re-enter the bucket, which facilitates full release of product into the discharge. Standard hole diameter is equal to the size of the bolt mounting holes in vent pattern #1, all other vent patterns will have 11/32” diameter holes unless otherwise requested by the customer.


  • Drilling any diameter hole over 13/32″
  • Bolt Hole centers closer than 1-3/4″
  • Side drilled buckets except standard peanut buckets
  • Special Venting requirements such as extra holes, change in hole diameter, etc.
  • Quoted prices subject to change due to special drilling and venting requirements
