Bear Iron Works Grizzly Rock Screen With Adjustable Sizing Removable Screen - Cub

The Bear Iron Works Cub Grizzly Rock Screen is a rugged, equipment-assisted screening solution designed primarily for skid steers. Built for contractors who need to separate rocks, debris, gravel and other oversized material from usable soil or aggregate, the Cub lets you process material directly on the jobsite without relying on powered screening equipment.

The Cub uses solid steel screening bars rather than hollow tubing, providing greater impact strength and helping maintain consistent screen openings under repeated use. Its square-welded design is engineered to minimize bar deflection, material funneling and rock jamming while allowing material to flow freely across the screen.

With a standard 3-inch screen spacing and optional removable screen system for finer material separation, the Cub can be used for everything from rough rock separation to producing screened soil and finer aggregate. The removable screen uses abrasion-resistant crusher mesh and can be changed without a traditional bolt-on mounting system.

Bear Iron Works identifies the Cub as its most popular Grizzly model and the first in the line designed specifically around skid-steer applications. It can also be used with suitable tractors and other equipment where machine capacity and bucket dimensions are appropriate.

Which model should you choose?

The Cub is the best fit for contractors running standard skid steers who want a versatile jobsite rock and soil screening solution.

Choose the Growler if you use smaller equipment or need a more compact screen.

Choose the Cub for standard skid-steer applications and general construction, landscaping, aggregate separation and material reclamation.

Choose the Mama if you're operating larger equipment such as backhoes, large skid steers or utility tractors and need additional screening capacity.

Choose the Papa for full-size loaders and heavy-duty aggregate, riprap and high-production screening.

Features

• Solid Steel Screening Bars: Built with solid steel rather than hollow tubing for greater impact resistance, stronger welds and longer wear life.
• Designed for Skid Steers: The Cub is purpose-built around skid-steer screening applications and is recommended for machines starting around the CAT 226 / Bobcat S450 class.
• Efficient Material Separation: Separates oversized rocks, gravel and debris from usable soil and aggregate directly on the jobsite.
• Anti-Clogging Design: Square-welded bars resist deflection and help prevent material from funneling or becoming lodged between the rails.
• Standard 3-Inch Spacing: Provides efficient coarse screening without requiring a powered screener.
• Optional Fine Screening: Add a removable crusher-mesh screen for more precise screening applications.
• Tool-Free Removable Screen System: Optional screens use a hook-style mounting system that allows operators to remove or exchange screens using their equipment.
