MC FOTO Expandable Core Grip
The MC FOTO Expan Core Grip incorporates two expandable core units. One side has a large toothed gear to which a nylon link chain affixes, permitting convenient raising and lowering of the background paper roll. The other side has an adjustable tension drag. The double core units are unique in that when the overall screw on which the drive unit is mounted is tightened the drive expands from a minimum of 1.8" to 2".
To accommodate cored paper rolls in any length, all you do is insert the Expans at both ends, tighten up until they're snug and mount the entire assembly on your background holder hooks.

PES EXPAN CORE GRIPBy: Adrian on 21 March 2015Easy to install and use. Chain does fell stretchy when used with a full 6 metre vinyl backdrop but it works fine. A little more detail could be supplied on the website. e.g. both fittings will extend about 135 mm beyond the backdrop roll when installed so on a 2.7 m wide backdrop you need a room 2.97 metres wide as a minimum. They also work perfectly on a ceiling mounted system. Great product.
PES Expan Core GripBy: Rob on 1 February 2015This is the first expan core I have purchased (approx. 2 weeks ago). The build quality seems sturdy enough and supports a vinyl roll with aluminium core without any obvious problem. Weakest point appears to be the plastic chain, although it functions well enough when used carefully even though it feels stretchy once the tensioner is applied. Easy enough to assemble. Instructions would help - I was under the impression that you could lock rotation using the chain, however this needs to be done using the tension screw on the opposite side of the roll. Also, it's halpful to note that there are two stand holders provided with the kit. I purchased these holders separately believing that none were provided. For the price, this is a product that suited me very well and I am satisfied so far. : )
