Mercury Floor Machines A-167-1 BOSS Floor Machine Apron – 15", 4 lbs, with Bumper

Mercury A-167-1: 15" Apron with Bumper for BOSS Floor Machines

The A-167-1 is a 15" replacement apron with integrated non-marking bumper for Mercury BOSS-1 and BOSS-2 floor machines. At 4 lbs — lighter than the 17", 19", and 21" aprons — it is suited for the narrower cleaning zones where those larger sizes cannot operate. The same three-thumb-screw mounting system that fits all BOSS apron sizes makes the A-167-1 interchangeable on the same machine body in under two minutes.

Where the 15" BOSS Apron Fits in Narrow-Zone Cleaning

The 15" apron handles access zones where the 17" apron is too wide — laboratory bench corridors, walk-in cooler interiors with narrow lane clearance, service hallways between fixed racking, and residential areas of commercial facilities with door frames narrower than standard commercial openings. Compared to the 13" apron (A-163-1), the 15" apron covers 2 additional inches of floor per pass and is 1 lb heavier — minor differences, but relevant in zones where the machine runs straight passes rather than navigating turns. For facilities operating the BOSS machine across a full range of floor widths, the complete apron set (13", 15", 17", 19", 21") provides a machine that transitions between open areas and tight access zones without purchasing additional floor machine equipment.

BOSS Apron Series: Width Progression and Selection Logic

The BOSS machine's apron system spans five widths: 13", 15", 17", 19", and 21". Each step up adds 2" of pad width and 1 lb of apron weight. The machine weight — not the apron weight — determines total pad pressure; apron selection determines only the pad width per pass and whether the machine fits through a given access point. When selecting apron width: use 21" for open areas where width is not a constraint; use 19" when the 21" is marginally too wide for doorways; use 17" for service corridors in the 18"–20" access range; use 15" for access lanes in the 16"–18" range; use 13" for the tightest access points. If a facility only needs two aprons, the 19" handles most doorways and the 13" handles the tightest access — the 15" and 17" add coverage in between for operations with more varied access constraints.
