A good look at the flush-joined grids of the optional Foyer Panel.

Rodney and his new sweetheart Ms. Mullens have taken a stroll in the gardens when he learns of her hidden past. The grids. A grid phobia, and he wonders What Else? What else is she hiding and why can’t he find a normal girl. Just a normal sweetheart. Is that asking so much?

The Garden Arbor #15-2 shown with Garden Gate style #20, with a keystone. 1-⅝” thick arbor trusses

Here we see the radius of the gate arch considerably softer than that of the arbor, primarily because the gate width is 60″. To match the gate radius to that of the arbor would have raised the gate arch, and consequently the overall height of the arbor beyond that allowed by local codes. It’s never a cut-and-dry option.

Garden Arbor #15-2 is configured to allow a lighting fixture mounted to the underside of the arbor. To have your arbor wired for a lighting fixture with fully concealed wiring, as shown below: add $325. The wiring is embedded and will stub out coiled from the mounting cap with sufficient length to run the length of the site post and junction at grade to the source.

The same Four-Post Garden Arbor photographed 15 years later. The homeowner originally applied a single application of a Cabot Heartwood oil, which gradually grayed out to the weathered look below. Finishing the Prowell products does not prolong their life or preserve their structural integrity.

This is what happens if you do not insist your installer read the install guides. Here, the mounting lags were ignored, and the arbor was simply seated onto the posts and that was that. But . . . in time the vines and climbers will exert enough persuasive torque to actually lift the entire arbor off the posts.
