It's a post and screw, works like it should and arrived when they said it would.
Finding the Spider Camera Holster has enabled me to use both my camera bodies and keep them safe. I no longer have them dangling around my neck, setting a camera on the ground or needing someone to hold it for me. This has allowed me to quickly change bodies depending upon the need at the time. I have reached out to customer service several times and received the help that I needed to find the right combination of products for me. Thank you Spider for a solid safe solution for me!
I bought the pin to add to my existing holder so that I could hang the camera from either hip. It was easy to install, and does the job for which I purchased it.
