Buying Guide
- What size post caps do I need? Measure the post diameter and wall thickness to match a 12.60″ square footprint or the exact width specified by the mold or cap.
- Shallow vs. deep caps: Choose Model 1 for lighter applications and Model 2 when you want a deeper, more substantial cap with enhanced visual weight.
- Integrated base options: If moisture protection at the base matters, consider models that include a base cap or base integration.
- Material and finish: Fiberglass-reinforced concrete gives a stone-like appearance with weather resistance; ensure color and finish suit your landscape.
- Installation method: Some caps require exterior masonry adhesive; confirm compatibility with your post material (wood, metal, etc.).
- Maintenance: Look for water-shedding designs and smooth edges to minimize water infiltration and debris buildup.
- Costs and availability: Mold sets provide flexibility but require proper curing and concrete mixtures; consider availability of replacement parts.
