Inquiry (采购产品): Snap Button I cannot use the information form on your website because it will not accept my email address, so I am trying to contact you this way. Part Information Request: Snap Button E-Dual Type Tube Shape: round Tube size in inches O.D.: 16 mm .62992 inches Tube size in inches I.D. : 13 mm .51181 inches Tube wall thickness in inches: 1.5 mm .059055 inches Head diameter in inches : appox. 6 mm .23622 inches but I will take your advice on this Head height in inches (OF OUTER HEAD - Head 2):appox. 6mm .23622 inches but I will take your advice on this Head height in inches (OF INNER HEAD Head 1): 1.4 mm 055118 inches Working load: not sure what this means. In what type of application are you planning to use our product ? I have two pieces of tubing, one is 13mmID/16mmOD and the other is 16mmID/19mmOD. The smaller one slides inside the larger one. I need to anchor the smaller one inside the larger one at a certain point using head #1 (to prevent the product telescoping when in use). Then when required the buttons are pressed and the tubes are allowed to telescope inwards, when once again they are anchored by the snap button's head #1 to prevent opening. The double type is needed to keep the snap button permanently attached to the inner tube by having the head #2 anchored in a hole in the inner tube. Your catalogue does not state whether the measurements are inches or millimetres and both the "Standard" and "Metric" catalogues show exactly the same figures for all products. Can you advise please what size of E-Dual type snap button I need for this project? I actually would prefer plastic but have googled until goggle-eyed and cannot find any manufacturers, although I know that plastic snap buttons do exist (used in telescoping pool cleaning poles, etc). **** Hidden Message ***** Susan Davies 18 Sun Street BrinsmeadQueensland 4870 AUS Company: Serdona Pty Ltd Title: Ms Phone: 61 7 4034 3722 Fax: 61 7 4034 3711 E-mail: catsonvacation@optusnet.com.au **** Hidden Message ***** catsonvacation@optusnet.com.au
