Product Overview

Z20P2431NGD – 4" Food-Safe High-Temperature Oven Rack Caster – 3-1/8" × 4-1/8" Plate


The Z20P2431NGD is the industry-standard, OEM-style high-temperature oven rack caster commonly supplied on commercial bakery racks and oven racks from original equipment manufacturers. This model is designed as a direct replacement where dimensional accuracy, heat resistance, and food safety are required.

It features the most common oven rack mounting plate size: 3-1/8" × 4-1/8", allowing direct replacement without drilling or modification. This is the plate size used on the majority of commercial bakery and oven racks in the field.

The wheel is manufactured from a food-safe, high-temperature epoxy resin compound suitable for use around consumable goods. It is designed to withstand elevated temperatures, steam, oils, and repeated wash-down cycles without degrading or contaminating food-contact environments.

OEM-Correct Replacement for Bakery & Oven Racks

This caster matches the original configuration used by many commercial rack manufacturers. It is commonly installed on:

  • Commercial bakery racks
  • Oven and proofer racks
  • Food service and processing carts
  • High-heat, wash-down environments

Important: This caster uses the 3-1/8" × 4-1/8" mounting plate. If your rack uses the larger 4" × 4-1/2" plate, this model will not fit.

Plate Size Verification (Critical)

Most bakery and oven racks use the 3-1/8" × 4-1/8" plate, but some manufacturers use a larger 4" × 4-1/2" pattern. Always measure your existing caster plate before ordering to ensure proper fit.

Food Safety & Material Compliance

The wheel compound is designed for use around consumable goods. Its non-porous, high-temperature material resists absorption of oils, moisture, and food byproducts, making it suitable for regulated food environments.

Patent Information

This caster design is covered under U.S. Patent 3,052,650, reflecting the original engineered configuration used in commercial oven rack applications.
