Left fin stopper specifications

Choosing the right left fin stopper

Check which side of the door the fin sits on when viewed from outside. Order the left hand version if the fin is on the left. Send us a photo if you are unsure and we will confirm.

Fitting tips

Glass door hardware must be fitted to toughened glass with the correct cut-outs, and always with the gaskets supplied between the metal and the glass. Never over-tighten fixings on glass. Check the door swings freely and closes smoothly before you finish, and adjust the closer or pivot if needed. If you are unsure, ask a professional glazier to fit your left fin stopper. For more guidance, see the Glass and Glazing Federation website.

Need help choosing?

Not sure which fitting you have? Glass door hardware often looks similar but differs in size, handing and cut-out shape. Send us a photo of the whole door and a close-up of the old fitting, along with your glass thickness, and our team will help you identify the correct replacement before you order.

Care and maintenance

Clean your left fin stopper with warm soapy water and a soft cloth, then dry it to keep the satin finish looking new. Avoid abrasive pads and harsh chemicals. Check fixings and gaskets during routine maintenance, as worn gaskets can let the glass move and cause wear.
