The Monument 4562P GRIP+ is a pair of stepped hexagonal fittings, nickel-plated for durability. These fittings measure 8mm, 9mm, and 10mm, as well as 11mm, 12mm, and 13mm. They are designed to connect to the Monument 3240U and the 4537G GRIP+ shorty swivel handle, effectively extending the reach of Monument 3240U box spanners. This extension allows for easier access to Monobloc tap back nuts.
