Jade Spider Grate 7in Cast Iron Replacement - Durable Range Part

In this review of the Jade Spider Grate, the reviewer focuses on durability and compatibility for commercial and heavy-use home ranges. The bottom line is simple: this cast iron grate is for cooks and service technicians who need a robust replacement part that resists warping and handles frequent high heat. Measured at an outer diameter of 7 in and weighing just over 3 lb, it is a straightforward, heavy-duty solution when an original grate is worn or damaged.

Key Features

• Cast Iron Construction: The rough cast finish provides excellent heat retention and stands up to repeated heating cycles without deforming.
• Exact Diameter: The 7 in outer diameter makes it a direct fit for compatible JADE hot plate and range models, reducing installation guesswork.
• High Quality Build: At 3.26 lb, the substantial weight signals a durable part that stays stable under cookware and heavy use.
• Model Compatibility: Designed to work with several JADE hot plate and range series, which simplifies sourcing parts for repair or maintenance.
• Serviceable Replacement: Offered as a simple part reference for technicians, making identification and ordering easier during repairs.

Who It's For

This grate suits commercial kitchens, foodservice technicians, and serious home cooks who use JADE range or hot plate models and need a dependable replacement part. It is particularly useful where a high thermal mass and a non-warping cooking surface are priorities.

It is not aimed at casual users who prefer lightweight, decorative grates or at owners of non-JADE ranges without matching burner geometry; those customers should verify model compatibility or seek manufacturer-specific alternatives.
