I need external louvres to fit 160 round ducting. This one (GALCWL-160) looks right, except that its price on your web site is way out of line with the 150 and 200 sizes. Please check this.

Please check this.answer nowA Hello John, Thanks for the heads up regarding the pricing error - I am not sure what happened here but you are correct that the pricing here was out of line with the other products in this category. I have reverted the item back to its original price and it should now be viewable on the website. If you had added the item to your basket you may need to refresh the page or remove and then re-add the product.Please do not hesitate to contact me if you would like to discuss the rest of the ducting that you plan to order and we can make sure that everything will fit together nicely.Kind regards, Michael
Does this come in stainless too?
Do you have any in stainless similar to this?
-
A Hello Paul Thank you for your question. The weather louvre with mesh does not come in stainless steel but we do two bull nose vents in stainless steel the codes for them are QS127, QS129
How would this be fixed to a stone wall
-
A Hello Brian Thank you for your question. For a normal install you would pilot two holes either on each side or top and bottom and then drill and screw to the wall. However if you have an unusual wall type then we recommend that you contact us.
