Quad Lock iPhone Case – iPhone 16 – Twist-Lock Compatible

This Quad Lock iPhone case for iPhone 16 is a protective everyday case that also functions as the mounting interface for the Quad Lock system. It’s built for riders who want a single case that works both on the bike and off, without switching cases or adding stick-on adapters. Unlike standard phone cases, the Quad Lock interface is molded directly into the back of the case. That allows the phone to mechanically lock into any Quad Lock mount, keeping it secure during riding while remaining slim enough for normal daily use. Key Features Integrated Quad Lock twist-lock interface Impact-absorbing TPU outer shell with rigid polycarbonate core Slim profile suitable for everyday carry Soft microfiber lining to protect the back of the phone Edge-to-edge protection Full access to all ports and buttons Compatibility & Use Notes Designed specifically for iPhone 16 Compatible with all Quad Lock mounts Mounts sold separately Not compatible with non–Quad Lock mounting systems Phone must be fully rotated to fully engage the locking mechanism Service / Ownership Context Because the case is part of the mounting system, keeping the locking interface clean is important for consistent engagement. For riders using their phone regularly for navigation or ride tracking, this setup offers better security and less wear than clamp-style holders.
