Simpson Strong-Tie CC66 Column Cap For 6X Beam, 6X Post
Best for projects requiring strong uplift performance on 6x beam and 6x post configurations. This cap uses certified welds to provide reliable loading capacity and features uplift enhancements for wind or earthquake scenarios. Bolt spacing adheres to NDS code requirements to ensure optimal performance. This makes CC66 a solid choice for structural work where code compliance is a priority. Choose this if your setup uses larger posts and beams and you need verified weld strength.
Best for: builders needing certified welds and code-aligned bolt spacing for 6x configurations. Limitation: requires proper bolt layout per NDS guidelines; misalignment can reduce performance.
Simpson Strong-Tie LPC4Z ZMAX Galvanized Adjustable Post Cap For 4X
An excellent option for projects needing adjustable post caps on 4x posts. The adjustable design offers greater connection versatility, and its universal design eliminates the need for right and left variants. It’s noted for being stronger than traditional angled nails or screws and helps avoid end-grain nail penetration. This makes LPC4Z a good pick when you require precise alignment and easier installation on standard 4×4 post systems.
Best for: installers seeking adjustable, universal post caps to simplify alignment and reduce end-grain nails. Limitation: adjustable range may be less suitable for non-standard post dimensions beyond 4x.
2 Pack Simpson Strong-Tie CC68 Column Cap For 6X Beam 8X Post
This 2-pack is suited for multi-post projects requiring robust uplift resistance and consistent weld quality. It mirrors the CC66’s emphasis on certified welds and uplift support, with a configuration that’s well suited for larger post-to-beam connections. The advantage here is cost efficiency when working on several posts in one project.
Best for: projects needing multiple caps with strong welds and uplift performance. Limitation: may be over-specified for very small decks with simple connections.
4Pcs 4×4 Post Cap Tie Bracket Heavy-Duty Pergola Connector Bracket
Designed for outdoor structures like gazebos, pergolas, and decks, this 4-pack provides a strong connection between wood posts and crossbeams. Made from thick galvanized steel with a powder-coated finish for rust resistance, it supports standard 4×4 posts and typical cross beams. Its 6-inch wide by 3.6-inch long by 7.1-inch high footprint ensures a stable anchor for outdoor projects exposed to weather. Best for: outdoor builds where rust resistance and heavy-duty support are needed. Limitation: intended specifically for standard 4×4 posts; non-standard dimensions may require different brackets.
Simpson Strong-Tie CC46 Column Cap For 4X Beam, 6X Post
CC46 is a robust option for configurations that pair 4x beams with 6x posts. Like the CC66 and CC68, it emphasizes certified welds and uplift resistance to meet wind and seismic loading. The bolt spacing aligns with NDS code requirements to ensure proper performance, making it suitable for more demanding attachments where both size and uplift matter. Best for: projects needing reliable weld strength and uplift-ready caps for larger post systems. Limitation: similar to CC66 in requirements; verify compatibility with your exact beam/post sizes prior to purchasing.
Buying Guide
What should you consider when choosing post caps and column brackets?
- Post and beam dimensions: Ensure the cap or bracket matches your 4x or 6x posts and beams. Mismatches can reduce load transfer and appearance.
- Uplift and wind/seismic performance: Look for certified welds, proper bolt spacing, and uplift ratings aligned with local code requirements (NDS or local standards).
- Material and finish: Galvanized or ZMAX-coated steel offers corrosion resistance for outdoor use; consider powder coating for added durability in harsh climates.
- Installation approach: Adjustable or universal designs simplify alignment; consider whether you need right/left variations or can work with standard components.
- Quantity and budgeting: For larger projects, packs or multiple caps may reduce total cost while ensuring uniform performance.
Quick decision tips
- Choose CC66 or CC68 for higher post/beam configurations that require strong uplift performance.
- Opt for LPC4Z when you need adjustability on 4x posts and a universal design.
- Use the PUXILEM brackets for outdoor structures needing heavy-duty, rust-resistant connectors.
