Choose your Blackline Slatwall External Trim Colour
Complete your slatwall installation with the Blackline Slatwall External Trim Chestnut, designed to provide a clean, protective, and seamless border for exposed panel edges and transitions. The Chestnut finish features a rich, reddish-brown wood tone that seamlessly complements chestnut-finish slatwall panels, creating a refined and cohesive look for your wall paneling.
External Trims are essential finishing components used to protect and conceal exposed edges, corners, and terminations on the exterior of a slatwall installation. By covering open panel ends, the External Trim enhances the overall aesthetic while shielding vulnerable joints from moisture ingress, dirt, and weather exposure. This small detail provides a sharp, professional finish that elevates the entire slatwall project.
Manufactured to a premium composite specification, this trim features a durable outer protective layer that offers superior resistance to fading, scratching, and harsh outdoor elements. Designed to maintain its pristine appearance with minimal maintenance, it comes in a versatile 3.66m length (55mm width, 46mm thickness) to fit standard slatwall layouts and installation requirements.
10-Year Warranty
Blackline Slatwall products are engineered for lasting performance and durability. Backed by a 10-year warranty, our slatwall range offers long-term protection, quality, and peace of mind for your property.
We use our own in-house delivery service to ensure your order arrives safely and on
time. Estimated delivery is 2–4 working days from order confirmation.
After installation, you may notice a slight lightening of the product’s colour. This is a natural part of the weathering process, caused by initial exposure to sunlight. This temporary change typically settles within 6 to 12 weeks. Once this period has passed, the product’s colour will remain stable and will not experience further discolouration under normal conditions.

Aug 8, 2024Great experience. Didn’t originally deliver to my area but and they sorted the situation out right away! I also asked if I could pay cash on delivery which they were more than accommodating for. Products were just as shown and described and I’m over all really happy. Especially for price and quality.
