Pest Control WorldwideStainless Steel Rat Flap for Drains, Rat Gates for Sewers, Single Steel Valve, 4 inch Rat Flap(100mm/110mm), Non-Return Valve

This product was really easy to fit. Looks excellent quality and will hopefully work now we think the rats were getting in through that pipe so can only come down from the loft and not up it but think they are now gone. Such a good invention. Would highly recommend. Will hopefully last years.

It was bargain price for one of these and was a slack fit but I bolted a u shaped strip of metal to the top bolt and that made it a tight fit. It's a few weeks now and no rats have managed to eat my toilet waste anymore.

Fitted very well, appears to be well made and should do the job.cheaper than many others will use again when needed

Did not fit

Seem to be expensive for what they are But these were the Lowest price of this design. Too early to comment on success of device. Very easy to Fit. Says Stainless Steel ( I worked in Steel Industry ) so If true , they should last along time.

Ordered on behalf of the experts that were dealing with the pest control issue. Easy to fit and I’m assured does the job perfectly
