The retainer bars are an option and are not required for installation or use of the Ultra-Drain Guard.  They are helpful when installing and removing the Ultra-Drain Guard as they will keep the unit in place whenever the grate is being lifted or put into place.

The Ultra-Drain Guard is held in place by the grate on top of the catch basin.  So steps must be taken before lifting the grate to remove the Ultra-Drain Guard or it will fall to the bottom of the basin once the grate is lifted.  By using the retainer bars and placing them through the handling straps you can prevent the Ultra-Drain Guard from dropping when the grate is lifted.

The Ultra-Drain Guard, High Capacity Model can be used for drains up to 54″ x 54″ (Keep in mind that the standard drain guard works with drains up 30″ x 40″).  Excess skirt material can be left in place and will actually act as a “pre-filter”.  If a neater appearance is desired, excess material can be removed by cutting it with a heavy-duty pair of scissors or a utility knife.

Those are lifting straps and help in removing a full Ultra-Drain Guard from the catch basin.  Note:  The Ultra-Drain Guard, High Capacity Model can hold up to 300 lbs.  Caution should be taken when removing it.  Larger/heavier loads may require backhoes, forklifts or other equipment for removal.
