Pro Studio Solutions EZ Pro Softbox Speedring Insert, for Speedotron Black Line 202VF, 206VF, 102, 103, 105, Brown line MW3R, MW3U, MW3UQ, M90, M90Q, M11 Strobe Flash Light, Speed Ring, Soft Box

I know a couple of reviews complained about the size but these were a perfect fit for my glow modifiers. Great product at a reasonable price.

The ring works perfectly with an excellent fit and finish.

I've order several of these and they all work perfectly with my Speedotron Blackline studio strobes 102 heads. I use several different brands of lighting and these rings allow me to use my softboxes and beauty dishes on all of my lights, studio strobes, monolights and speed lights. Fits perfectly.

Well ALL speedrings have a standard size recess. to name a few Photoflex, Westscott, Speedotron, are all the same, designed to fit a square,rectangle,strip or an Otca in all of them they all have a recess to hold an insert that mounts to various inserts, Like this one. The mount of this one is for Speedotron blackline however it is too big in diameter. All inserts are 5- 5/8" inch this one is just under 6" (5-15/16") inches so it will not fit into the recess.The recess holds the insert via 4 fiber/plastic washers(nuts and bolts) and are designed to let the Softbox rotate. Again this is too big and does not fit. I dont know if these are miss cut but all of my speedrings have the same recess and all of the inserts I have (5 in all) are the same. This is an oddball size, For the price I will try to grind it down, but is a shame as the chrome plating would prevent friction and rust. I will contact the seller to see what they say. Be warned this insert is TOO big!

Bought these before to adapt to numerous of my diy modifiers for my Speedotrons. Good product!

Great Product, works great.

fits and performs as expected.
