Buying Guide
What type of aluminum framing suits my boat?
Consider opening size, mounting surface, and exposure to corrosive elements. Smaller portlights benefit from slim, corrosion-resistant frames, while larger windows may require reinforced sections for durability.
Which corner protection is right for my deck?
Pontoon decks with rounded corners typically use 90-degree corner caps. Check if your corners are standard 90° or require a custom fit. Durable powder-coated aluminum caps resist wear from docking and wave action.
How do I install portlight screens and corner caps?
Most of these products are designed for straightforward installation with basic tools. Confirm whether screws, gaskets, or screws with rubber seals are included. For best results, clean the mounting surface and verify alignment before fastening.
What makes aluminum a good material for deck framing?
Aluminum offers a balance of strength, light weight, and corrosion resistance in marine settings. It resists rust, reduces overall weight, and maintains structural integrity under vibration and spray.
Are universal-fit options better?
Universal-fit corner caps ease installation across different deck sizes but verify compatibility with your specific edge thickness and corner radius. If in doubt, measure your deck corners and compare with product specs.
