The REVOLVER is the only secure brush extender that stays rock solid over time. Included is a Revolutionary 360° rotatable paint roller, the only of its kind. Paint high and hard to reach areas without the use of a ladder more than 50% of the time. Paint overhead trim such as gutters, fascia, beams and rafters 20x faster. Securely holds most sizes and handle styles of paintbrushes (brush not included) and easily changes to 8 different positions. Paint on top of surfaces too by inserting the brush in the rear of the barrel. What's the trigger for? Pull trigger to release and lock the Speed Pro mini roller (included) to quickly change to 16 different angles. Mini Roller accepts most sizes, types and brands of standard ¼” core mini roller covers (covers not included). Turn the roller vertically to paint the top of walls within ¾” of the ceiling, rather than the 2”-3” gap like other rollers. Less gap means less brush cutting in, better roller nap finish, no ugly brush marks. Revolver and mini roller fit all standard 3/4" threaded poles, quick connecting extension poles and most threaded broom handles. Ergonomic comfort grip provides a relaxed, fatigue free overhand grip painting position. After an hour or two, no hand fatigue means cleaner, straighter brush lines. The big grey brush tightening bolt doubles as a very handy pail hook for both brushes and rollers. Made of high grade 'Nylon 6' plastic is super tough and lightweight. Speed Pro rollers fit in any gallon zip seal bags for 100% sealed storage for weeks, wet and ready to paint when you are. Additional attachments, Speed Pro- Jumbo Mini Roller 3/4" core, ASIN# B01FUZAKG8 is also available. Brushes, roller covers and extension pole not included.
