Ultra-Drain Guard® Retainers

Keep Drain Guards in place even with storm drain grating removed

Most Ultra-Drain Guards are held in place by pinching the material of the unit between the storm drain's grate and the catch basin. The advantage of this is that it's simple. Lift the grate. Place the Drain Guard. Lower the grate. Done.
The one consideration with this type of setup is what happens to the installed Drain Guard when the grate is lifted? Well, if you don't plan ahead and use the built-in lifting straps, it's going straight to the bottom of the catch basin.
Ultra-Drain Guard Retainers eliminate that issue. These steel bars span the opening of the catch basin and secure the Drain Guard whether the grating is in place or not.
Key Features:  
  • Heavy-Duty coated steel retainers mount on inside ledge of catch basin — securing Drain Guard when the grating is removed or installed.
  • Two sizes of telescoping retainers adjust to fit any size storm drain.
  • For use with all Drain Guards (NOTE: Drain Guard is not included).

Frequently Asked Questions

Why do I need Drain Guard Retainers?
"Need" is a relative term.  Retainers are not requiredfor using/installing any of UltraTech's Drain Guards.  But they can make thing a lot easier.

The majority of Drain Guards are held in place by pinching the fabric (of the Drain Guard) between the catch basin ledge and the grating on top of the basin.  That makes the initial installation quick and easy since there are no extra components needed.  However, it can present a challenge when it's time to remove the Drain Guard.  If you don't plan/think ahead, the Drain Guard will drop straight to the bottom of the catch basin as soon as the grating is lifted.

The retainers help avoid a solution for this.  By utilizing the lifting straps built into every Ultra-Drain Guard, the retainers will keep the Drain Guard at street level whether the grate is in place or not.


Are there any drains that the Drain Guard Retainers won't work in?
Any drains that don't fit within the two ranges (22" - 36" and 36" - 62") will, of course, NOT work with the reatiners. It's always a good idea, if possible/practical to lift the grating off and taking a look at the catch basin ledge as well as the bottom of the grating before you purchase the retainers.

Some catch basins only have a ledge on two sides of the opening instead of on all four sides.  Also, depending on the location and weight capacity, the grating may have a large support rib underneath.  Depending on the size and shape of that rib, it may prevent the use of the retainers.


How do the retainers adjust to fit different sized drains?
The two sections that make up the retainer fit inside each other and slide freely.  So the size can be adjusted very precisely.  There are no notches, holes, pins or other adjustment devices that would preclude the "perfect" fit.
