# Baseline 15mm LW Baseplates Baseline 15mm LW Baseplates holds 15mm lightweight rods at the correct distance from the center of the lens. ARRI dovetail slot on the bottom attaches to the [Baseline ARRI Dovetail](https://www.mid49.com/products/baseline-arri-dovetail "Baseline ARRI Dovetail") or other ARRI standard dovetails using a top-load locking mechanism.  [Baseline ARRI Dovetail](https://www.mid49.com/products/baseline-arri-dovetail "Baseline ARRI Dovetail") is the lower ARRI mounting plate which can attach to tripod plates using 1/4-20 or 3/8-16 screws or ARRI standard bridgeplates with centered or offset screw spacing. ARCA dovetail slot on top holds the [ARCA Dovetail](https://www.mid49.com/products/baseline-arca-dovetail-14-5mm-height "ARCA Dovetail") and can be top-loaded, or installed from the back by sliding in. When sliding in from the back, a safety pin will engage with a pop when properly installed. Adjust the position, then lock the ratcheting thumbscrew. Top-loading can be achieved by loosening the thumbscrew, pulling out on the ratcheting knob, and turning the thumbscrew until ARCA clamp has opened fully. Reverse the process to tighten. Center screw slot on ARCA Dovetail accepts 1/4-20 and 3/8-16 mounting screws, and a vertical rod hole clamps to 1/4-20 lens support posts for adaptors like Metabones, etc. ## Products in this collection -
