Adjustable lengths Very easy to use and highly functional when fitting things into tight spaces. Be careful not to sperate th e2 ends - this product is so well made with the interlocking double walls that the tolerance is tight ... meaning re-assembly after a mistaken over-extension can be fiddly! Can't buy better!

MD 150mm Flue system This review is for the whole 150mm twin-wall flue system which has this adjustable length, a 45 degree elbow, a 45 degree T + cap (separate) and 3 x 1000 m lengths with associate flash, and support brackets.
Customer service was excellent from the initial query to the delivery. Will buy again.

Adjustable length Great product. The adjustable clamp does buckle the outer surface if too tight. A screw tightening clamp is a better option. Also need to watch out for clearance through a wall collar!
Very efficient delivery system to France. Also very helpful in store.
