Review the product description, intended application, dimensions, materials, compatibility information, and installation requirements before ordering. If you are uncertain, contact us with details about your project and the product you are considering.

Are your products suitable for outdoor use?

Some products are designed for exterior applications, while others are intended only for indoor or protected areas. Check the individual product page for information about weather resistance, moisture exposure, temperature limits, and suitable surfaces.

Can I use these products for structural repairs?

Certain fasteners and connectors may be intended for structural applications, but suitability depends on the building design, load requirements, local codes, and installation method. Structural repairs should be evaluated and completed by a qualified professional when appropriate
