Inquiry (采购产品): Slip-On couplings Dear Sir; I represent a company that is interested in acquiring slip-on steel EMT couplings in the larger sizes, 4" etc. that DO NOT have a center stop or ridge that stops the end of the conduit from going further than center... We do not know if such a fitting exists or can be UL listed, however an installation technique we are developing would be greatly enhanced if we could find such a fitting. Can you help? **** Hidden Message ***** Billy Baskin 4462 Corporate Center Drive Los Alamitos , CA 90720 USA Company: Dynalectric Los Angeles Title: Warehouse Manager/Purchaser Phone: 714-236-2231 Fax: 714-484-2392 E-mail: bbaskin@dyna-la.com **** Hidden Message ***** bbaskin@dyna-la.com
