  • What buyers say about SMALLRIG Super Lightweight 15mm Railblock

    For the money, this works well, smooth finish on the parts, nothing missing that I can see, but how hard is the aluminum relative to screw holes in the future?

    I got this one after I sent it back, because it broke the first time I used it, but it's great and I need it to do what I need it to do.

    The items are very well made and at a great price, but I think one of the most important things is that they can be pulled out and adjusted to a different clock position if you want to continue turning in tight spaces.

    The slides are on my rod 60mm wide and include an Allen wrench and 4 bolts.

    The item is ok, but first time it is not overpriced, it is just $14.99, so I mix and match with other manufacturers, I recommend this item to others.

    Common Questions


    Is it possible to attach something to the smallrig a6300 cage?


    Yes, via the 1/4''-20 screw.


    I have a shape rig for the a7sii and are distances between rails universal? Can I use it?


    Yes, it's the standard distance.


    I want to know what the difference is between rod clamp 1806 and 840.Are the smaller threaded holes different in size?


    Hope that will help, the rod clamp 1806 has a screw.


    Is it possible to put this on my niceyrig steady shoulder pad?


    The shoulder pads have threaded holes, so this rod clamp can be screwed to them.


    Is it possible to attach 2 of these to the side of my dslr sholder rig if there are holes lined up for mounting them to the back of my zoom h4n?


    I thought the H4n only has one mounting hole on back, so 2 wouldn't line up.
