Exitex Capex Snap Down Glazing Bar 10-25mm
Low in cost, high in quality!
Strong aluminium base bar with durable, maintenance-free uPVC top capping and end cap. Secures and seals polycarbonate sheets along the timber rafters of wooden conservatory, lean-to roofs, carports and shelters. Suitable for glazing of 10mm, 16mm, 20mm and 25mm thickness.
Base Bars are screwed to the top of timber rafters to provide a seat for the roof material, before Top Cappings are pushed down firmly, until their toothed legs grip the relevant locking point on the Base Bar up-stand. Weather sealing is provided by rubber flapper seals that are coextruded along the top capping, whilst the underside is sealed by long-lasting EPDM rubber gasket that fits along either side of the base bar.

Fitting the Exitex Capex Snap Down Glazing Bar
The following is offered as a guide to typical installation, and not intended as comprehensive fitting instructions.
- Cut Base Bar and Top Capping to same length as polycarbonate sheet
- Fit EPDM rubber gasket (may need to be torn into two along the length) to track on either side of Base Bar
- Pre-drill fixing holes along length of base bar and between toothed up-stand
- Fixings should be no more than 500mm apart and within 100mm from either end
- Screw the Base Bars to rafters using 5mm wood screws
- Peel protective film from edges of polycarbonate sheets to prevent being strapped by glazing bar
- Position Top Capping over Base Bar and push legs firmly into up-stand to ensure seal
- Fit end closure to polycarbonate sheet, using thin bead of silicone on underside of top face
- Apply a little silicone sealant to underside of End Cap top lip and push firmly onto glazing bar
Additional considerations
- It is assumed that polycarbonate sheet length is cut with allowance for a 50mm overhang into the gutter.
- A glazing width deduction of 21mm from rafter centres will allow for Base Bar up-stand, plus expansion and contraction.
- Fixing buttons can be used along eaves or purlins to secure sheets that are large, or in exposed locations.
- Capex Snap Down works best with roofs over 5° pitch.
