The Antares Extension Tube ET2TL extends any 2" accessory by 2.25" with twist-lock retainer. Works with any type of barrel: smooth, grooved or tapered. Accepts 2" filters.
2"x2.25" extension with twist-lock retainer. Threaded for M48x0.6 filters.
Excellent fit and finish. The tightening ring is quite smooth in both tightening and loosening. Holds very securely when tightened. I have tightened a Powermate in the unit and pulled quite hard on it - the Powermate doesn't budge.
Twist lock takes this to a new level. Excellent piece.
