P287 Glazing Bar
A hidden fix version of the P280 glazing bar.
An aluminium structural glazing bar into which multiwall polycarbonate, solid polycarbonate or glass can be fitted. When glazing with multiwall polycarbonate the P287 glazing bar is capable of spanning up to 3.2m between fixing points. For applications longer than 3.2m span, an intermediate cross purlin should be installed to create a further fixing point, alternatively use the 287 cap on top of the 288 base which can span up to 4m.
The P287 can be supplied either as a pre-pack complete with the aluminium base bar and bar cap, both with gasket fitted and an end plate or as loose individual items The P287 glazing bar can also be supplied as a hipped glazing bar which uses the same cap however we change the standard gasket to a half round gasket which allows the sheet to be fitted at an angle.
Standard Glazing Bar
| Reference: | P287 |
|---|---|
| Colour: | Mill Finish, White or Brown |
| Length: | 3m, 4m and 6m |
| Span: | 3.2m |
The P287 glazing bar consists of an aluminium base bar (ref.283) and a shaped aluminium glazing bar cap (ref.287), a screw cover clip (ref. 400C), gaskets and a mechanically fixed end plate.
The base bar is fitted to the ridge and eaves support, the glazing sheet sits on the gasket and the cap is drilled at intervals no more than 400mm apart. Screws are then fitted through the cap into the central stalk of the base bar. The length of screw differs with each thickness of glazing sheet. The screw cover clip is slid into the screw channel to hide and protect the screws.
For applications without good ventilation i.e. enclosed sides, it is recommended that a uPVC thermal underclad be supplied to clip onto the base bar to minimise the risk of condensation forming. This is then known as the P287U glazing bar.
The P287 glazing bar is supplied as a pre-pack in 3m and 4m lengths with gaskets installed and as loose items in 6m.
Hip Glazing Bar
| Reference: | P287H |
|---|---|
| Colour: | Mill Finish, White or Brown |
| Length: | 3m and 4m (and 6m as non-standard) |
To make the bar suitable for a hipped application, the gasket in the glazing bar cap and base is replaced by a half-round gasket and re-named as P287H.
The P287H is supplied as a pre-pack in 3m and 4m lengths and as loose items in 6m. The 3m and 4m pre-pack consists of the aluminium glazing bar cap and base, hipped gasket and a screw fit end plate.
Colour Options
Mill finish as well as polyester powder coated white (RAL9910 satin) and brown (RAL8040 satin) are available as standard. We can also supply the aluminium painted to a specific RAL colour although this may be subject to a minimum quantity requirement and surcharge.

Glazing with Glass
The P287 glazing bar is suitable for use with glass. Twinfix cannot advise as to the spanning capability of the glazing bar or at what centres the glazing bars should be placed. We recommend that a mechanically fixed end plate similar to our SB-MEP end plate be fitted at the foot of each bar to stop the glass from slipping.
