These clear replacement h-bars hold glazing panes in place on the Halls Silverline greenhouse models.

Measuring 610mm long, this is a pack of four h bars. A small but invaluable spare part of your greenhouse that may need replacing. This part is used in different areas on a Halls silverline greenhouse depending on the size and glazing type.

Supplied in a clear colour finish, complimenting both silver, green and black framed greenhouses. Alternatively, see our black retaining h bar instead.

H Bar Usage

As per the assembly instructions of Halls Silverline greenhouses, these h-bars are labelled as part number “452”, and named as "glass retaining 'H'". These replacement h bar sections are commonly used for the below areas on a Halls Silverline greenhouse:

  • For Connecting Two Horticultural Glass Panes on the Roof
  • For Linking Glazing Panes Together in the Door

If you need a retaining bar to connect a toughened glass pane to the acrylic curved panes, see the glass to acrylic retaining strip instead.

How To Replace a H Bar

Fitting them is straightforward.

  1. Firstly, remove any old retaining h bars.
  2. Take one of your new h-bars in hand and hook it onto the side of the first adjoining glazing pane.
  3. Then, hooking the opposite glazing pane into the other side of the h bar edge.
  4. Push the h-bar down gently, into the frame, where you can now (where needed) further securing any glazing with greenhouse clips, also known as W Clips.
