110mm OsmaSoil PVC‑U Strap Boss - Wavin (Grey) - 4S319G

A strap boss fitting designed for insertion into an existing 110 mm ring‑seal socket post-installation. It creates a secure, leak-resistant branch access point using a captive EPDM seal and maintains proper fall orientation via a built-in keyway. Ideal for connecting additional waste lines where a bossed pipe wasn't initially fitted.

• Captive EPDM prevents seal displacement during fitting.
• Internal keyway guarantees proper fall alignment.
• Conforms to key British and European drainage standards.
• Small profile (84 mm square, 134 mm long) for tight-fitting installations.
• Suitable for retrofits or last-minute branch additions.
• Inserts into OsmaSoil sockets for branch connection after original installation.
