Buying Guide
What size do you need? For shelf supports, 3″x3″ brackets are common, but larger 4″x4″ brackets provide more load capacity. Consider thickness and hole spacing to match your screws and beams.
Galvanized vs stainless: Galvanized steel offers good corrosion resistance at a lower cost. Stainless brackets resist rust longer but at a higher price. For outdoor or humid environments, prioritize galvanized hot-dip finishes.
Load capacity matters: Look for brackets with a high gauge and multiple holes to distribute weight. Always factor in wood integrity and screw size when estimating load.
Install tips: Use proper screws matching the bracket holes. Pre-drill where needed to avoid splitting wood, and ensure brackets are level for balanced load distribution.
Budget and quantity: If undertaking multiple projects, a larger kit often reduces overall cost per bracket. Pair brackets with appropriate fasteners to maximize durability.
