This package of 2 x Sashmate telescopic rod sets are designed to be used instead of standard solid rods allowing the Sashmate® Top Hung to be used with short complete openers of approximately 650mm in height. Rod set 1 = 650mm to 880mm and rod set #2 = 880mm to 1240mm. These telescopic main rods can also be combined with the Sashmate Side Hung to reduce minimum working height to 650mm.
