The ETBB28 is a low-profile saddle tungsten bucking bar for backing rivets along a raised bead, tube, or curved feature. At 3.15 lb and 4 x 1.625 x 0.938 inches, it brings the backing mass of a much larger steel bar to the rivet, so shop heads form clean with less shock to your hand.
A knurled channel along the top cradles the work while dense tungsten backs the rivet tail from below. At roughly 2.5 times the density of steel it seats firmly for clean shop heads with less recoil.

Questions about this bar
What is the ETBB28 tungsten bucking bar used for?
The ETBB28 is a heavy tungsten bucking bar for larger rivets and thick structure, delivering maximum backing mass in a hand-held bar. Hold it flat and square against the rivet tail so the shop head forms evenly.
How much does the ETBB28 bucking bar weigh and what size is it?
The ETBB28 weighs 3.15 lb and measures 4 by 1.625 by 0.938 inches. You buy a bucking bar by weight, and tungsten packs that weight into a far smaller block than steel.
Why is the ETBB28 made of tungsten instead of steel?
Tungsten alloy is about 2.5 times denser than steel, so the ETBB28 delivers the same bucking mass as a steel bar more than twice its size. The compact mass means better access in tight structure and less shock to your hand.
