Will the sweep be long enough?

The gap between the bottom of my shower door and shower threshold is 7/8". Will the Shower Sweep With Drip Rail work in my shower? Is it too big a gap? Conversely, if the sweep is too long, can I cut it?

The sweep used with the 10-325 is 3/4" high, not including the rounded end that fits into the drip rail. So this would be very close, but I believe it would just be enough room between the drip rail's bottom and the floor (1/32" to spare). Let me know if that makes sense, or if you have any other questions.

Thanks for the information. Do you think that 1/32" space would allow water to get onto the floor? Your sweep is the last hope for fixing our issue. I tried gluing a new flexible rubber sweep onto the existing drip rail (twice), but each time the sweep allowed water leakage. The sweep was touching the shower threshold, but it did not hold a good, stiff shape, so allowed water in.

Hey there. I took a measurement from the from the center of the mounting hole in the metal channel to the bottom of the vinyl sweep and came up with 1", so it looks like you should just make it. Also, the metal channel has that drip rail to help shed water away. Take note when installing this drip rail you will need to use the 33-071 screw. Be careful when drilling through the door you don't drill into the shower door glass. Alternatively you could also use a type of double stick tape to attach this drip rail.
