ProMaster Arca-Type Quick Release Plate (Model 10493 / Grey)
Precision-Machined Aluminum Quick Release Camera Plate – Standard Arca-Swiss Compatible Dovetail Design, Full-Coverage Anti-Twist Textured Rubber Grip Surface, Integrated Shoulder/Wrist Strap Loop Slot, Removable Dual Safety-Stop Screws, Standard 1/4″-20 Camera Mounting Screw with D-Ring/Coin Slot, Direct Replacement for ProMaster iota, Chronicle, and XC-M Tripod Kits & Ball Heads (Excellent Condition)

The ProMaster Quick Release Plate (Model 10493) is a precision-engineered mounting plate designed to provide secure, vibration-free camera attachment across a broad array of professional support systems. Serving as the standard factory replacement plate for ProMaster iota, Chronicle, XC-M 522, XC-M 525, and XC-M 528 tripod series—as well as the XC-MH26 and XC-M30 ball heads—it features an industry-standard Arca-type dovetail geometry. This universal profile ensures seamless interchangeability with tripod heads, gimbal heads, fluid video heads, and quick release clamps from ProMaster as well as leading third-party manufacturers.

CNC-machined from high-grade aluminum alloy with a durable grey anodized finish, the plate is fitted with an edge-to-edge, textured rubber anti-twist top pad that cushions the base of the camera body while preventing slippage and twisting during vertical portrait orientation framing. For added field security, two removable steel safety-stop screws are installed on the underside to prevent the plate from inadvertently sliding out of an open clamp. A built-in lateral slot accommodates sling-style shoulder straps or hand grips without interfering with clamp mounting, while the captive 1/4″-20 mounting screw allows tool-free tightening via an integrated folding D-ring, slotted coin drive, or hex key.
