3608 is a standard, replacement quick release plate for ProMaster XC-M 522 & XC-M 525 tripod kits as well as XC-MH26 and XC-M30 ball heads. It uses a dovetail design (arca-type) which is also compatible with a huge number of heads, gimbals, and other accessories from ProMaster as well as other manufacturers. 

This Quick Release plate is precision machined using high-grade aluminium and it has a soft, grippy, anti-twist pad around its entire top surface. An integrated strap slot works with a variety of shoulder straps and hand grips. Two safety bolts are installed in the bottom of the plate to prevent it from accidentally sliding off a head. These bolts are removable if you so choose.

This plate is also available in a variety of other, super-cool colours. 3657 is silver.
