Base Mounted Type (Flanged) Push-Pull toggle clamps use a plunger mechanism to produce a positive straight-line action. They have the advantage of having a low profile, using side or end clamping and so are most suitable for application having a height restriction. Features include: Body and linkage components on the light duty range are zinc plated to resist corrosion. Pivot points are fitted with hardened steel or stainless steel rivets to maintain accuracy and provide a long life. Red vinyl hand grip with cushion rib profile for improved user comfort. The heavy-duty range has ductile cast iron bases for strength and rigidity.
