I have a 1-2" gap in my hardwood floor after I needed to swap a larger register with a smaller one. 1
I need to replace a 12" x 10" supply register grill with a 12" x 8" supply grill (because I need a booster fan grill and the largest size they come in is 12" x 8") leaving me with a 2" gap along the bottom of the register grill.
What's the easiest way to fill that 2" gap in the hardwood floor opening in a way that doesn't stand out? If I can find a nice reducer frame, that would be nice but I can also take suggestions for other simple suggestions as well.
The smaller size doesn't matter with the supply duct since the duct below is a round oval about 10x4... with the supply duct before the elbow being a larger rectangle.
Here is the original supply grill before I will replace it with a shorter grill.
Here it is after it's been replaced
Should I put a frame around it to make it look nice and since the floor around the frame needs some cleaning, or can I wedge or nail in some wood in and then finish to match somehow?
