• Outside diameter of 22 mm as a ground seat in the drill plate
• Bore rounded on both sides to form B, so the bush can be fitted either way round
• Dimensions to DIN 179, so existing bushes can be replaced size for size

• Drill templates for assembly work on site
• Guiding twist drills and reamers in the jig
• Repair of worn drill plates by replacement of the same size
