MANUAL SHUTTER ASSEMBLY Description: this is a nice shutter that allows to close or open the 2" hole pulling/pushing the rod. It is meant to be mounted through the 3 front holes (for instance, see 2nd picture). The rod stays in place in any position you may set the device. Besides, it has two allen screws that allow the amount of strength that should be applied to the rod in order to engage/disengage shutter itself. All-metal and very sturdy! Measures: see pics (in mm). Condition: normal usage marks. Nice working condition. Note: these items have been de-greased, cleaned, re-greased (with special oil better than original grease) and checked for missing or damaged parts. Then tested and verified ok. Good functioning is garanteed. OFFERS: feel free to send me offers, since doesn't allow for offers in industrial category.
