around obstacles – Visual width indicators keep operators informed of paving width – Extenders are equipped with vibration and heat – Angle of attack adjusters enable the extenders to match the main

screed texture

SCREED PLATES

– Main plates are 457 mm (18") wide (front to back) – Extender plates are 229 mm (9") wide (front to back) – Standard hardened alloy steel plates resist abrasion – Optional high strength plates for increased durability – Curved screed plate design ensures smooth flow

VIBRATOR SYSTEM

– Provides initial compaction – Located on main screed and extenders – Adjustable range of 0 - 3000 vpm – Vibration on extenders is synchronized to match the main screed

SPRING-LOADED END GATES

– Delivers an adjustable force allowing the end gates to follow the

paving surface – Ensures contact with the mat to create a confined joint – Eliminates protrusions, enabling the extender to pave close to curbs

and obstructions – Replaceable wear strip ensures performance

FRONT-MOUNTED EXTENDERS

– Narrow front-mounted extenders easily draw in material when

paving around obstacles and quickly extend when increasing paving widths, prevents mix from being trapped in front of the main screed

THICKNESS CONTROL SCREWS

– Equipped with spinner handles for quick, easy adjustment – An adjustment of 25.4 mm (1") requires 8 turns – Choice of left or right hand depth control threads to suit

operator preferences

POWER CONTROLS

– Crown angle, +10% to -3% – Extender slope percent, +3% to -10% – Extender height, 6.4 mm (0.25") increments

EXTENDER ANGLE OF ATTACK ADJUSTMENT

– Extenders are equipped with angle of attack adjusters – Easily match mat texture and quality of the main screed
