I offer a box of Hodgson Flexistrip, butyl glazing tape in ‘off white’ colour. There are 11 rolls, each with 15mm x 2.5mm x 19m of tape, totalling 209m. Specs available here
, datsheet here
The tape was manufactured in 2011 and supposedly only has a shelf life of 12 months, hence why they are offered for free. However, since the tape is supposed to glaze a window with a lifespan of 20-30 years then I’m sure they will be perfectly good to use. The tape is still sticky.
You’re welcome to collect or I can post for small fee of £6.
If you’re near Gloucester, Cheltenham or Ross-on-Wye then I’m happy to deliver.
