 Simpler carriages with a limited disappearing function were initially provided for smaller weapons, the balanced pillar for the 5-inch gun M1897 and the Driggs-Seabury masking parapet for the manufacturer's 3-inch gun M1898.However, these could only be retracted at a specific traverse angle (90° off the emplacement's axis), thus could not be used in action.Due to the mount's undesired flexibility when fired interfering with aiming, both types were disabled beginning in 1913 in the "up" position, with installations circa 1903 and later having received pedestal mounts.
