Brett Martin 112mm Roundstyle PVC Internal Stop End in Black
Used to seal the open side of a fitting in Brett Martin’s 112mm Roundstyle system, such as a running outlet or angle, this internal stop end fits securely inside the component to create a watertight seal. For gutter ends, an external stop end should be used instead.
This internal stop end is designed to cap off the open end of a fitting within Brett Martin’s 112mm Roundstyle rainwater system, ideal for sealing off running outlets, angles, or other components where the gutter run terminates within a fitting. It creates a watertight seal and helps prevent unwanted leaks at the edge of the system.
Internal stop ends are inserted into the fitting itself, rather than over the end of the gutter length. For closing off the end of a gutter section directly, an external stop end should be used instead.
Part of the Roundstyle range, this fitting is made from durable, UV-stabilised PVC with a black gloss finish and is suitable for domestic buildings, including both new installations and refurbishments. The system is lightweight, easy to fit, corrosion-resistant, and backed by a 10-year guarantee.

Installation tips
Push the stop end firmly into the open side of the fitting until fully seated. It should sit snugly inside components such as running outlets or gutter angles to form a reliable, watertight barrier. Ensure all seals are clean and intact before installation.
Handling
This Brett Martin rainwater system is made from PVC, making it lightweight and easy to handle. All guttering and fittings should be handled with care at all times to avoid not only damage to the product but also preserve the appearance.
Storage
All Brett Martin products should be stored in conditions that will prevent the risk of damage and impact the appearance. Fittings and long items, such as gutter sections and pipes, should be kept in a cool, dry place. Gutter and pipe lengths should also be laid horizontally while in storage on a smooth, level surface to prevent distortion.
If storing gutters, pipes and fittings outdoors, ensure all items remain in their original packaging until installation to protect them and maintain their original appearance.
Maintenance
Regular maintenance of your rainwater gutter systems is essential, with cleaning recommended at least once a year. In areas prone to significant windborne debris, such as falling leaves, more frequent inspections and clearing may be necessary.
The high-gloss finish of the guttering helps resist dirt build-up, but when external cleaning is required, a mild detergent solution is suitable for removing surface grime without damaging the finish.
