Buying Guide

Match post size to bracket

Choose a base designed for your lumber (4x4, 6x6, 8x8) to ensure proper fit and load transfer without modifying hardware

Prefer galvanized or rust-proof steel

Galvanized or rust-proof finishes resist corrosion in outdoor conditions and extend anchor life on decks and fences

Check mounting method

Decide between bolt-down bases, ground spikes, or floor flanges depending on whether you mount to concrete, wood, or soil

Look for heavy-gauge construction

Thicker steel (14-gauge or heavier) and reinforced welds improve shear strength for railings and load-bearing posts

Verify included fasteners and compatibility

Confirm whether timber screws, anchor bolts, or required hardware are included or must be purchased separately for your substrate
