"Amazing! This is the actual large pool fitting that attached to part number 10744 to make the large pool suction/strainer part that is so very hard to find these days. It is made very well and built to last however please note it states on the part that it’s for use for one year. This is absolutely the large piece you have been looking for. It won’t tell the measurement in the description or specs so I wanted to let everyone know. The small pool strainer grid can screw onto the threaded strainer connection but only on the small inner ring and it is so much smaller you won’t get the same surface area in order to produce a good suction to truly circulate the pool water at a great rate. So glad to have found this! Price is amazing too especially in comparison to sellers on eBay who charge approx 15.00 plus tax and shipping for a part that cost me less than 4.00. Hope this helps someone in determining the best choice for a large pool strainer grid "

"Bought this to stop leaves and larger items from getting thru to the pool filter. Works perfectly and screw right onto the output port. "
