RAM Mounts Cameras Motion Sensors Devices Tough-Ball with 1/4-20 x .25 Threaded Stud RAP-B-379U-252025 with B Size 1 Ball

Threaded portion looks longer in photo.

Perfect

i read the reviews about the bolt being shorter than what is shown in the picture but i ordered it anyway. it is shorter there the picture shows. be warned. i still can use it though.

Works well and allows me to attach my insta360 selfie stick to the RAM ball clamp

Just screws in good price

I looked at the product picture and figured Id received what I paid for.

AS to be expected of a RAM product.

I asked my local kayak shop what ball it was I needed for my Jackson Big Tuna Yak. They told me this one would fit and they were right. Its getting plenty of use.

Item arrived very quickly. Very easy to install. Looks and feel very durable.

RAM mount makes some top notch products
