Rubber rings enhance stability during use, suitable for clean gaps in demanding materials. Wedges and spacers cover split stone, granite, marble and concrete, helping improve efficiency and reduce labor in quarry work. Steel spacers are heat treated for hardness and toughness, delivering durability and long service life. Ideal for quarry, construction and home projects; these spacers accommodate different types of stone and concrete. Use scenarios - In quarry operations, use with wedges and spacers to stabilize and guide the splitting of granite, marble or concrete blocks, aided by rubber rings for added stability. - On construction sites, deploy spacers to maintain even gaps and ensure accurate alignment when installing stone and concrete components. - In home projects, work with various stone and concrete types for tasks such as patios, steps or countertops, using the set for stable, durable results.
